Ubuntu :: Browser Handle Heavy Java Usage ?

Jul 21, 2010

I'm looking for a browser than can handle heavy java usage. Firefox doesn't seem to be able to handle heavy usage anymore . Chromium does a decent job, but its just so different from Firefox I just can't get used to it. I have been trying to get used to chromium for over 2 weeks but can't because of the huge difference. So what other browsers can handle heavy java usage? On windows kmeleon was my go to browser to give you an idea of the browsers that I like.

Fedora :: PulseAudio Update - Heavy CPU Usage

Jan 29, 2010

I have Seamonkey set to play a .wav file when mail arrives. Since the latest update to pulseaudio, whenever mail arrives part of the sound plays, then one of my processor cores goes to 100% running pulseaudio. When I kill that process, the system returns to normal. This happens every time a sound is played.

General :: Big Cpu Usage But Top Shows No Heavy Use Process

May 6, 2011

I have been running to a strange problem. For a few days, a few times a day something seems to take over my machine. Suddenly I can't type, or the key shows up about 5 seconds are being pressed, music players halt, etc. In anticipation, I had top and htop running. Sure enough, when this business begins htop reports all 8 cores firing at near 100% for a few minutes. However, top is telling me nothing about who is too blame. The cup%sy on top shows heavy usage, but the top processes are nothing remarkable, mostly just top and htop and conky, all running at around 1 or 2% on average. I am a bit puzzled as to why I can't see the cpu hog so that I figure out what is going on. My question then: Are there some processes (in kernel space?) that don't show up in top, yet which could be hogging the cpu?

General :: Diagnosing Heavy Cpu System Usage?

Jul 26, 2011

I have been encountering lots of heavy system cpu usage. It is sporadic, last for about 10 minutes, and brings everything else to crawl (latency of even typing characters into an editor or a terminal is painfully slow). My computer is an i7 quad, and all 8 logical cores fire at near 100% during these periods. I can see the usage clearly with htop. The red bars in htop indicate system use (I have attached a screen shot for an example). However, as there is no process per se, I have no clue what is causing it.

It is something I have to fix as the computer becomes unusable periodically throughout the day.I One thing to add, I am using the computer as a ltsp server on ubuntu, attaching to it using two thin clients. There is always heavy ethernet traffic through the second ethernet card. I don't know if this is related. However, I do think all this problem began when I installed the ltsp and switched to using a thin client.

Slackware :: Installing Java Error - When Trying To Run A Java App With The Firefox Plugin - Browser Crashe

May 29, 2011

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.

Debian Programming :: Memory Usage When Running Java Program

Jun 28, 2013

I have a java program that runs on Debian as a background processor. Yesterday the Java program stopped running. I looked at the memory usage, the system only had 5MB memory left, so my guess is that the java program ran out of memory to use.

However, after we restarted the java program, we could see that the free memory count started to go up. It kept going up from 5MB to over 400MB. The increase of memory happened slowly, when I measured it, I could see that with each minute passing by, there were a bit more memory added into the free memory pool, and meanwhile, the java background process was running.

I wonder why this would ever happen. It's as if our java program first brought the machine done because it consumed all the memories, then after restart, it starts to give back memories.

Ubuntu :: Java Doesn't Recognize Default Browser?

Mar 17, 2011

I'm using SeaMonkey instead of FireFox, and this won't change. SeaMonkey is set to be the default browser in Preferred Applications I use a java chat client every day (.jar), which has a button that opens an appropriate web address.

The problem is, it opens that site with FireFox instead of my desired SeaMonkey.

The client runs fine with openjdk and sunjava too ( I have both installed ), but they both open sites with FireFox. In Sun Java 6 Plugin Control Panel I set the SeaMonkey launcher as "Command to launch default browser", but the client still opens sites with FireFox. As for OpenJDK, I haven't found any way to modify settings.

Ubuntu :: XVFB Served Remotely To Java Enabled Web Browser

Nov 1, 2010

What I have is Xubuntu running as a VM with VirtualBox on my Windows 7 Media Center that is always on. I am trying to be able to remotely access an X display on that box to do network auditing/ various linux stuff from the various places I go. I would like it to be as simple as possible and leave no trace on the remote computer, so what I would like is to use a java-enabled browser to connect to an xvfb on xubuntu with SSL encryption. I almost got it working using cherokee/x11vnc/desktop.cgi but it only works once or twice and I get network errors even on localhost. I would rather just not have X running all the time on the VM and just have an xvfb display waiting/created when I log in remotely from a browser.

Fedora :: Java Engine For Browser - Add Exception ?

May 24, 2010

I want a internet browser to open a site that needs java engine,firefox has not this and also galeon :

The certificate is not trusted because it is self-signed.

(Error code: sec_error_ca_cert_invalid)

* This could be a problem with the server's configuration, or it could be someone trying to impersonate the server.

* If you have connected to this server successfully in the past, the error may be temporary, and you can try again later.

Or you can add an exception

You should not add an exception if you are using an internet connection that you do not trust completely or if you are not used to seeing a warning for this server.

If you still wish to add an exception for this site, you can do so in your advanced encryption settings.

How i can add exception or it is better to say me that :is there any browser instead of internet explorer for linux??

Ubuntu Installation :: Missing Rights To Run Java Applet In Browser After Upgrade To 10.04?

May 7, 2010

I'm having a very strange error after upgrading to (K)Ubuntu 10.04.. basically Java Applets don't work in any browser (tried with Firefox, Chrome and Opera). The applet loads (plugin and JVM detected by all browsers) but it is grayed out. After trying all possible solutions I could think of (including installing alternatives jvm) I tried to run the browser as superuser: the applet is then working correctly. So somehow it seems to be a user right problem, but I'm not sure where this is coming from, both java (sun-6) and the browsers were installed and working ok in 9.10. Here is the directory list of /usr/lib/jvm/java-6-sun/jre/lib/i386

Code:

drwxr-xr-x 2 root root 4.0K 2010-05-07 14:03 client
drwxr-xr-x 2 root root 4.0K 2010-05-07 14:03 headless
drwxr-xr-x 2 root root 4.0K 2010-05-07 14:03 jli

Security :: Digital Certificate - "can't Set The Browser Java Is Enabled And So On"

May 10, 2010

Girlfriend with a problem: she needs to sign up at the unemployment office in Spain. She is here in China. But for reasons unknown, she can't access the bit which she needs to. It says: 'can't set the browser' Java is enabled and so on, we read the instructions. On her windoze computer, she has a digital certificate. I copied it onto my mem-stick. When I try to copy it from my mem-stick to my Linux machine, I can't. Not even as root! The folder is called 'certificado digital' and contains two folders:

Trash.(tilde)1 and VM_Ware_Workstation They both have some kind of encrypted stuff inside. Can this certificate be installed on my machine?? Trash has 5 things, VM_Ware_Workstation has 3 things. The guy who set this up for her told her she must use Mozilla. Is a certificate only valid with a particular browser?

Fedora :: Hidden Disk Space Usage \ Can't Figure Out Where The Runaway Usage Is?

Dec 10, 2010

I'm running into a problem where my system is running out of disk space on the root partition, but I can't figure out where the runaway usage is. I've had a stable system for a couple of years now, and it just ran out of space. I cleaned some files up to get the system workable again, but can't find the big usage area, and I'm getting conflicting results.For example, when I do a df it says I'm using 44GB out of 58 GB:

Code:
[root@Zion ~]# df -h
Filesystem Size Used Avail Use% Mounted on

Ubuntu :: Heavy HDD Activity After Login?

Oct 31, 2010

I'm running Ubuntu 10.10 on an Acer Aspire 5530G. On a fresh install, the HDD is silent after logging in and the desktop is immediately ready for use. A few days and updates later, after every login, there's heavy HDD activity that lasts about 20/30 seconds and makes it almost impossible to perform any other task. The entire desktop is visible during said event.

Not a big issue, however it bothers me a little. I've observed this behavior since Ubuntu 9.10. Anyone else experiencing similar problem?

Ubuntu :: Why Are Mac Programs Always Really Large And Heavy

May 26, 2011

It always seems to me that Mac programs use far more resources compared to gnu/linux and windows. for example the mac version of Firefox is 27MBs while the windows version is only 12. Also system requirements for programs often require far more ram for mac than they do for linux of windows. Is this just because they are poorly written? obviously, the mac version of firefox is just as good as the windows version. but if it's heavier, and does the same stuff, then it's worse, right? This probably has something to do with stupid formatting stuff.

Ubuntu :: Shutting Off Under Heavy Network Use?

Jun 5, 2011

so I've scoured the web and I can't seem to find anyone else having this issue. The issue:

Whenever my box is heavily using the internet, it seems to just wimp out. It shuts off and reboots.

When it's happened:I first deduced the connection to the network connection when I was trying to set up the system. When I tried an upgrade after the first time I installed the system, it crashed, leaving me with broken packages and all kinds of mess. So I decided to start over, and since I then had the network set up, I used the install latest version feature in the installer. If failed again. I battled issue this a couple of times before I opted to do updates in chunks instead of all at once. Success. Then I tried to download an entire website. You see, I had bought the computer to use as a test server for work. I ran wget, I believe. After a lot of recursive downloading, it decided to take another unauthorized break.

Now, I've got a minecraft server running too. It's been working pretty nicely, until lately. I've got a cron job set up to backup the server files with dropbox. Bad, bad, bad. The computer started acting up again, shutting off and rebooting. I figured it was having a hard time uploading to dropbox while simultaneously serving up the game. I moved the cron job from hourly to daily, and haven't had issues all day. Great. Until late tonight. It did it again while we were playing. It's relentless. So I went through the whole process of assessing damage. Luckily no damage. Then I went ahead and ran the dropbox script that didn't get to run while I was performing diagnostics.
