Software :: Java Daemon Dies Quietly?
Mar 3, 2010
I have a java processing running as a system service using a shell script to launch it. It runs under a user other than root via sudo The process runs just fine but seems to die sometimes for no apparent reason. When the process is killed normally (via service stop), it fires a shutdown hook in java and you can see the process going away. What I see in the log now is nothing the process just dies. When I checked the system.log I found at the same time this:
Code:
messages:Mar 2 19:43:22 beta_web gconfd (sifagent-16786): starting (version 2.14.0), pid 16786 user 'sifagent'
messages:Mar 2 19:43:22 beta_web gconfd (sifagent-16786): Resolved address "xml:readonly:/etc/gconf/gconf.xml.mandatory" to a read-only configuration source at position 0

I am running a recently built Debian 'Lenny' system 5.0.4.I used the gui install and asked for desktop/file server/ I created a raid 1 systemsing two similar drives.Finally I set up some samba shares to use from my (wife's) windows PC. I wanted to use PC names rather than IP adresses to access the shares so activated wins.My Debian system, called arcturus, did not appear in windows network places. After much trial and error and googling found that the nmbd service had stopped.'/etc/init.d/samba restart' reported nmbd not present, stopped smbd and then restarted both. My networking then all came to life.There is a Ubuntu forum discussion around this subject and the consensus seems that the samba daemons are starting before the network is properly established. I have installed a work-around by putting the restart line in /etc/rc.local.But I'm concerned that I have some kind of configuration error.The following is a section of my log.nmbd after setting logging to level 3:-
Initialising global parameters
[2010/03/07 14:22:56, 3] param/params.c:pm_process(569)
params.c:pm_process() - Processing configuration file "/etc/samba/smb.conf"

Am trying to set up a new system but am getting some strange behavoir. I've administered an Irix system before. I have opensuse 11.3 installed with gnome running. When i enter a bad user id in the windows login screen, the bad authentication causes the x window manager to crash and leaves the system in the ascii terminal mode login. I then have to login as root and do an init 3 , then init 5 to get the x server started again an get the windows login started. Has any one seen this behavior before and how can i fix this. Been hunting through /etc/X11/xdm to see what startup scripts could be causing this.

I'm new to Fedora and have just purchased a subscription to a GoDaddy Virtual Dedicated Server, which I'm able to control using SSH.I have a Java application that I want to run as a daemon on this VDS. Some google searching yielded a bunch of different methods of doing this, none of which I'm sure would be guaranteed to work with Fedora, so I was hoping someone here could give it to me straight and fill me in on the simplest way of doing this.What is the best/simplest way to run a Java application as a daemon on Fedora?

I have a java program which I need to run as a service or daemon. What is the most stable method to do it? It will be heavy processing socket programming which will be continously receiving data?

I can't get my Fedora 12 laptops to find bluetooth devices. In fact, I can't seem to get bluetooth working at all. This is happening with identical symptoms on two very different laptops, both of which had working bluetooth out-of-the-box with Fedora 10. Under Fedora 12 bluetooth silently fails and I have no idea how to debug it.
Here are the details:
- I'm running Fedora 12 on 32 and 64 bit machines. Both exhibit the same problem.
- I'm using KDE for both (this is the KDE spin of Fedora 12, the 32 and 64 bit versions)
I've got kdebluetooth installed. When I run
Code:
I see:
So I think the right programs are running.
Using the system menus, I can click on "Kdebluetooth4" but nothing happens. There is no bluetooth icon in the system tray, nor have I been able to discover how to add one (I thought clicking Kdebluetooth4 would do that).
I can manually run kbluetooth-devicemanager from the command line, and attempt to look for devices. The devices are never found (they are found by a nearby Windows machine, so I know the devices work). There are no error messages in the GUI, or in /var/log/messages.
On the console, I do see these messages when I run kbluetooth-devicemanager and attempt to discover devices:
Code:
Based on Google searches, that would imply a problem with dbus (I think) but dbus appears to be installed and running.

My bluetooth manager is dying every few minutes or even every few couple of seconds. This happens when i'm using bluetooth mouse. Mouse works correctly cause i've tested it in windows. In the attachment there is dmesg output. In dmesg i keep geting lines like:
Quote:
[ 1463.864082] usb 4-1: USB disconnect, address 10
[ 1463.864601] btusb_intr_complete: hci0 urb eddf2900 failed to resubmit (19)
followed by reconnecting both, USB dongle and mouse. Then it works for a while and dies again, over and over. It also happens when mouse it idle (no matter if 5 seconds or 5 minutes).[URL]..

I have two servers, both running Ubuntu 11.04 Server. One is a web server, running only a LAMP stack and openssh-server. The other is running server daemons for TeamSpeak and Minecraft. Today, the game server just went down. I can access the LAN by using SSH to connect to the web server, and ping it from there. However, it won't respond to SSH or anything else. The server is a few kilometers from here, so I will be going there tomorrow.
This happened once before, probably about a month ago or something. That time, the web server was running just fine, but the game server was powered off. I thought there had been a power disruption, because when I checked the BIOS settings of the game server, it wasn't set to resume after AC power loss. The web server was set to do this, so it made sense that it would be up and running again after a brief power loss. There were also some news reports about power disruptions in my area.
The thing is, I changed the BIOS settings of the game server to make sure this wouldn't happen again. When I go there tomorrow, I will bring the server back up. However, I would like to know what caused this so that I may prevent it from occurring again. Is there a logfile or something that I can check tomorrow to find the problem?

I followed this guide for my Acer Aspire One A150, and got wireless and suspend working fine:[URL]pendtoRAMThe only problem is that wireless is dead after resuming from suspend. I have to type:/etc/init.d/networking restart and after that everything works just fine and I get internet again.Is there a way to automate that process on resuming from suspend, so that I won`t have to type it manually each time?

My computer starts up and, usually, gets to a desktop (I can login). If I click on a folder to open it, the computer just dies. No power at all. Sometimes it doesnt even make it through the boot up stage, just stopping before getting to grub. This happens in F10 and F13, whether the grub is on the harddrive or a USB key. I'm thinking that I might need a new power supply, but I'm also wondering if I might have fried the CPU, which ran for several days at 50 or so degrees, (for sensor one on the little gnome panel applet). But it did go over 60 a couple of times and die from overheating. These higher temperatures were achieved by running CPU intense software, with the cores in use running at 100% each. The higher temperatures were from running it with all four cores.

Suse 11.2 - KDE 4.3.5. I have only one sound card. The only Pulse software that is installed is libpulse0 and libxine1-pulse. All sound applications work. Amarok, vlc, kaffeine, Skype etc. But then every say 6th. or 7th. boot the sound dies. On everything. Even the startup melody. When I go to Yast>Hardware>Sound everything looks in order but the test on the card makes no sound. But if I delete the active card then re-enable it everything works again.
I saved the working /etc files as *.works and ran the following script...
The only difference was a slight volume difference in asound.state (23 vs 27).
I thought I might try to diagnose it by doing a file search for file changes in the last 5 minutes immediately after I run the Yast re-enable.

I just loaded 11.2 & Kde 4.3. Installed both Kinternet and Kppp. My modem is a USR PCI HW modem 2976. Hardware Info shows it connected to /dev/ttyS4. I configured the modem with Yast as modem0. The user access box is checked for Kinternet Both Kppp and and Kinternet will dial out.
The connect response comes back from the ISP and either of the dialers will hang and the dial tone comes back. The firewall is showing modem0 in the External section. Nothing changes if I shut the firewall off.There's nothing in the dmesg I could find. Could this be a pppd permission problem?

Whenever I use Ubuntu, the internet seemingly dies out randomly. It never does this for windows 7. Could it be the router coincidentally dying, or is it a problem with Ubuntu?

I don't want to 'spam', (I had started a first thread about this some time ago), but I'm (still) experiencing problems with my internet: I can use the internet (I am connected through a simple switch) for some time, that is: surf the internet (in firefox) and download using vuze (azureus) but after some time, the internet connection 'dies' (downloadspeeds jump to 0b/s and I am not able to surf to any site in firefox). When that happens, the only 'solution' to this is restarting my pc.
I first experienced this when using ubuntu 10.04, so I thought that it was a 10.04 issue. I knew that when I had ubuntu 9.10 (karmic koala) installed, this didn't happen. So today, I installed karmic koala, but much to my surprise I am experiencing the same problem. I used 'lspci' to find out what NIC is in my pc and I found out I have the following NIC: 00:12.0 Ethernet controller: VIA Technologies, Inc. VT6102 [Rhine-II] (rev 78 ) I'm suspecting the NIC to be the problem. Is this probable? If so, I want to buy a add-in network card (simple one, not a gigabit card)

This can't be duplicated by anything specific, but I know it's not out of RAM at this point. The console keyboard and mouse are inoperational, and the monitor display seems to be going through test patterns, which turns out to be that the monitor is trying to sync to video output which is switching on about once a second. I can ssh into the box and see that many processes that were running are no longer running, for example gnome-session... and that once per second there is a new X process invoked with a different auth-for-gem parameter, per below:
/usr/bin/X :0 -nr -verbose -auth /var/run/gdm/auth-for-gdm-Kynptf/database -nolisten tcp
(one second later...)
/usr/bin/X :0 -br -verbose -auth /var/run/gdm/auth-for-gdm-GfBhRk/database -nolisten tcp

We have a NAS application which can be accessed by both HTTP and HTTPS connections.
The issue we are facing is that the tcp server instance that initiates the HTTP access dies after a few hours of inactivity(the NAS application was kept idle for around 10 hours). However, the tcpserver that launches HTTPS connections remained running.So the connection failed through HTTP access but the connection succeeded through HTTPS access.
The converse has also been observed where the tcpserver for HTTPS is dead but tcpserver for HTTP is running.
The version of tcpserver that we are using here is ucspi-tcp-0.88.tar.gz.
I have the following queries:
a)Has anyone faced the same problem before?
b)Is it an issue with this package version of tcpserver ?
c)Will upgrading to newer versions of tcpserver bail me out of the issue?
d)Also, could anyone let me know what are the possible causes for the tcpserver to die ?

Got a Zimbra server FOSS edition running on CentOS5.5. Everything was running fine until couple of days just found out that web administration interface just does not give the proper status. Web console says that none of the services are running which infact is not true. Only service that is not running is logger. This is the zmcontrol status output
Code:
antispam Running
antivirus Running
imapproxy Running
ldap Running
[code]....
Just the logger service is not running all the others are. But web admin interface shows all are stopped. Also it can be seen that zmlogswatchctl is not running. Starting it manually does not do any good. It does not start and it dies out by itself.I tried to google and found a couple of bugs related to logger and web interface but those were old and should have been done in this version 6.

I have a computer that running Ubuntu 10.04.2 LTS. Consistently after a couple hours the X desktop and GDM dies. It works fine on my other computers but this computer is an intel 2.4 GHz, 1.5 GB.

I updated my CentOS 5 box recently. But after then my Apache can no longer work; every time I try to start apache, it says started OK but then dies immediately and no error message at all. When I tried 'apachectl restartI', it says apache not running. It has been running fine before the update. I've looked at /var/log/httpd.log but there is not any message about my problem.

I try to install the java plugin but the java test pages show not installed. I have tried the openjdk-6-jdk package and the Oracle/Sun 1.6.0_26 version to no avail.
Is there some good instructions page someplace? I have yet to find a set of instructions that provides something clear that works.

Code: ~ $ /usr/java/jre1.6.0_25/bin/java -showversion Error occurred during initialization of VMjava/lang/NoClassDefFoundError: java/lang/Object
That's the error I get. When trying to run a java app with the firefox plugin, the browser simply crashes if it's the 64bit java or tells me it's not installed if it's the 32bit version.
I'm at a loss as to what to do. I think it has something to do with leftover gunk from a previous version I misinstalled(Is that even a word?) Anyway, the only thing that google could come up with was a solution for windows which laid blame on Bill Gates for having a bunch of pf (java prefetch) files stuffed into c:windows for no apparent reason. The solution was to delete them, but I can't seem to find the java prefetch folder in linux. The method I used is downloading the rpm from java.com the rpm2tgz then installpkg then cp libnpjp2.so to firefox plugins folder.
