Ubuntu :: 10.4 Gnome Desktop Is Spawning Multiple Processes?
Jul 27, 2010
This is the second new install of 10.4 on the same machine with the same issue. After boot, as soon as user logs into the desktop, sys mon shows cpu at 100 percent and a steady climb in ram usage. several processes are spawned continuously until all ram is consumed and then moves on to use scratch space.
Using top, the process count moves into over a thousand total processes. Some investigation using top, ps, and digging into the /proc folder shows a ppid of 1 If the machine is booted to shell, top shows 120 processes and is stable. Some of the processes running repetitively are the gnome toolbar, nautilus, and I wish I was clear headed enough to write the others down before I left work. I can certainly get a more complete list in the morning.
I have swapped out ram, and the processor with no success. I have also tried apt-get purge ubuntu-desktop then installing with apt, this did not resolve it. As mentioned at the top of the post, this is the second install with these symptoms. The first install started showing the issue about 10 hours after first boot. On this second install, all was working fine for a couple days before this started in.

I have running license server on my server. Right now I would like to write small status script and check if software is running.My software include 3 deamons:
1) daemonA
2) daemonB
3) daemonC
My script should check, if each of this deamon is running. If all deamons are running then script should print short output: "License server is running" if one of this daemons is not running, output should "License server is not running". Is it possible to write small loop to check it ? Let say, loop will take new daemon name from deamons pool and will check if its running. Sometimes I need to check more than three daemons of one Program and I dont know how to write good script for this. Maybe somebody could help me with this loop that in the future I could also use; daemonD, daemonE, daemonF.etc.etc. if all daemons from pool is running then..."Software is running"

my computer is often very slow, to the point of stalling. I tty'd in and when I ran ps -ef I noticed about 10 /usr/sbin/apache2 -k start I dont even want 1 apache running. Any suggestions why these are running, or how to stop it? Well, I can stop it with a sudo killall, but how can I make sure it doesnt happen again?

As an assignment i was doing a program to create two process using fork and pass messages between them using message queue.Did it worked well until my friend tried to copy it using scp.suddenly all hell broke loose as processes without ran syncronisation ie. in tech terms the process just wont wait wen a message queue is empty.it keeps on executing randomly.but after a reboot .. everything worked fine. until again i tried to do scp on my system on purpose. and again the program just went mad.

when I start my application it creates a message queue and forks a process. The child process reads multicast packets from the network and writes to message queue. The parent process reads packets from message queue and compares source ip and sequence number (it is part of payload) with last 64K packets received to see if it has received a duplicate packet. I am using message queue as a buffer because I do not want child process to drop any packets while it is comparing it with previously received packets. The message queue is large enough to contain 64K packets. To compare the old packets I am using array of structures as circular buffer. During a spike I may receive 100 - 120 packets per milli second.
When I run my application, the parent process keeps up with the child process, I can see that with "ipcs -q". After about 30 seconds it cannot keep up and the size of message queue keeps increasing until it is full. When I run "top" I can see that one CPU/core is hundred percent busy while other 7 cores are idle. It seems that both processes are running on same core and the child process gets interrupts everytime there is a packet on the net and starves the parent process.I am running RHEL 5. The system has 24GB memory and my application is the only application running on it. It is a HP G6 server.

I'm looking for a way in Perl to be able to take a list of servers, ssh multiple commands to it and store the results. If I do this process serially, sometimes one server will hang the whole script and if it doesn't, it still takes hours to complete.
I'm thinking what I need to do is make a parent loop that calls out a separate process that passes the server name to the child sub process and then executes all the commands I have defined in its own process. If one server 'hangs', at least that won't stop the script from doing all the other servers in the list.
I'm guessing using the fork() command would serve me best, however, all the online descriptions I have found have been vague at best.

Whenever I monitor my CPU's, it seems only the first is ever utilized, with the second always being at 0%.Does this mean it is not being used, or just not being reported as in use?Is there anything I could do to improve the situation if it is not being used as much as it could be?On Windows, I can assign processes to both cores, or either one. Is there a way to do something similar in Linux?

My server is really slow. When I did a top -c or ps aux, below shows up. Shouldn't there be only one? Shall I kill all those processes and leave only one?

The system in question is using Mint 9, but the forums there aren't as active and since its Ubuntu based I didn't think it would be a concern bringing my problem here. If this is an issue, apologies, lock the thread and I'll head over to the Mint forums.So I have an SSH server running on the system, but I only like to have it running at certain times, so I removed it from the rc scripts using the command: sudo update-rc.d -f ssh remove.
Anyway, later I found that SSH was turning on at boot time anyway. I checked the rc scripts manually and couldn't find reference to it. I then tried to stop the process using the command: sudo /etc/init.d/ssh stop which reported that it was working, but after checking the processes and consulting syslog I found that it was re-spawning after I had told it to stop.I found 2 ways to stop the process without it re-spawning:sudo initctl stop sshand sudo service ssh stopSo whilst I can turn it off at each boot, or script it to shutdown at login, I'm still wondering why update-rc.d isn't working

I replaced my gnome with openbox some time ago, some of the gnome utilities still boots at at the start and I love and use most of them. Still few of them are causing problems, how can I selectively disable from autostarting?Also which utility takes care of mouse speed? I keeps resetting my settings?PS; I did some research and fooled around with xinit files, tried to grep them out of the init stuff, no result...

I wrote a program that multiplies 2 matrices using multi-threads and another one using multiple processes and shared memory. Both in C.I need to find the total memory usage of these programs. I know of the top command, but when my matrices are relatively small they don't even show up on top because they complete so fast, how can I find the memory usage for these instances?Also, how can I find the total turnaround time of my programs

This is a bit complicated to discribe because I don't know the cause, but this problem has been happening for some time (over a few years and generations of kernals), with different Gnome distributions, including Ubuntu (and family) and Fedora. When using Gnome (and only Gnome), I frequently see the screen dim. At the same time, all processes will be locked up. This may happen for a second or two, or it make require a reboot. The mouse can usually move and the underlying program GUIs are still visible, it's just that one or more of the GUIs will be dimmed. This is usually most noticeable with a browser, but that may just be a coincidence.

I noticed this weird behaviour yesterday after the last update (not sure if it's really related, but I didn't notice this before).When I do a fresh start and log in - all the gnome related processes are DOUBLED in the memory Of course it causes weird errors, applet hanging or crashes, very sensible slowness while booting and operating, etc, etc.Basically I have 2 gnome-session loaded at once - one as a child process of gdm-binary and another separate one. Both sessions have all the child process loaded, so I turned out to have 2 Nautilus, 2 Metacity, 2 Gnome-panel, 8 python processes and all the set of applets are also doubled.

I need to spawn 2 processes in parallel and each takes an hour or so to finish. Is the following one of the correct ways of using `at` in a script run by crontab?
Code:
#!/bin/bash
# define the env var, cd, etc... assume everything ok up to this point
date +"The start time is %H:%M:%S"
rm -f a.fin
at now <<END_OF_AT
do_a &> a.log
[Code]....

In the gnome-system-monitor, on the "Processes" tab in the "View" menu, I should be able to choose between "Active Processes", "All Processes", and "My Processes". The chooses are all greyed out and I am only able to view "My Processes".I launched the app as root and had the same lack of choice.I also disabled SELinux and rebooted the machine.

nautilus starting up at login then spawning new instances till it runs out of memory. At one time I checked Startup Applications Preferences to Automatically remember running applications when logging out; I unchecked this thinking it was the problem; but it has not gone away; I have to kill nautilus, then the spawning will stop. Also I can not close nautilus; another instance will run; sometimes starting the spawn all over.

I have VMware server installed on this machine. I also have a Windows XP VM running all the time. I have it bridged so it gets a valid IP from my router and such and is in my network. I use KRDC to remote desktop to it and I make it full screen. However if I want to go back to my desktop I have to minimize KRDC.
Is there a RPD client out there I can use so I can go full screen on 1 desktop and have everything else on another desktop then use KDE's Desktop switcher or ctrl+alt+arrow keys to switch between desktops to flip between Windows XP and Linux without having to minimize?

When i logged into a gnome desktop i got this message: "The GNOME session manager was unable to read file:'/home/(desktop name)/ICEauthority'. If this file exists it must be readable by you for GNOME to work properly. try logging in with failsafe session and removing the file." What commands do i use for that? or do i need to do something else?

I have my Unity desktop just how I like it, but sometimes I like to log in to the Gnome (Ubuntu Classic) desktop. However, I was playing around with CCSM while in Gnome and I've totally messed it up, I have the Gnome panels and also the Unity launcher, it's a total mess. Is there a way to reset my Gnome desktop to default without affecting my Unity desktop?

is it would be possible create a Ubuntu dvd that contains the ubuntu server desktop and alternate install opptions, as well as all four main desktop environments (gnome, kde, xfce, lxde) and unity. since much of the data is redundant between each version cd's it would probably all fit on one disk. then all that would be needed is two disks one for 32 bit and another for 64 bit. i really think that this could work.

I'm running Fedora 15 with Gnome 3. I installed Gnome-Do using 'yum install gnome-do'. I opened it from the Terminal by typing 'gnome-do' but I keep getting an error message that says
Could not load desktop item: libgnome-desktop-2.so.17
Gnome-Do opens but it doesn't display any application I search for and when I try opening the Gnome-Do preferences, it quits.
I installed gnome-desktop-2.32.0-8.fc16.i686.rpm from here: [url] and then installed Gnome-Do. Everything works fine now.

I just installed Fedora 15 with the gnome desktop which looks like the android system for mobile phones, I installed wine which put the icons on my desktop but whenever I install a windows app it doesn't put an icon on my desktop for that particular application. How would I add an icon for those window apps so I can lunch them from the desktop, I don't know if you call that the desktop or just the program luncher either way how do I put an icon there so I can run those windows apps from there?

With xterm, I can do the following, and the scripts are executed sequentially in a single xterm: xterm -e 'script1.sh;script2.sh' But with gnome-terminal, when I do: gnome-terminal -e script1.sh;script2.sh It runs them in parallel in 2 different terminals. I've tried a few combinations of ", and ', around the scrips, but no difference.

there are some old PCs in the house that the Hard Drives are so bad, anything put on them stutter horribly (10min to load up thunderbird? No way). So, my idea was to set up some desktops on a PC (Intel Pentium Dual Core E2160, 4GB RAM, 750Gb in HDD space) wired to the network, and the "satellite" PCs could use a CD or flash drive with Puppy Linux (or something else, if you have any suggestions) and connect to the main PC.
This way, the files are safe from the failing HDDs, speed shouldn't be a problem, and being able to set up a print server would be icing on the cake. The one small problem is the best way to do it. Since I'm a newbie, I was just thinking some Virtual Machines (virtualbox right now, since I can't get KVM to work) with VNC server software. Keep in mind the satellite PCs aren't used for much storage of music and video files, mainly just email and internet, so the RAM and HDD space shouldn't be an issue (I'm not sure on the processor).
