Eclipse freezes Ubuntu, hard reboot required

I'm on a team of 6 developers and we are all using Eclipse Indigo on Ubuntu 11.04. At least once a day, if Eclipse is running, each of us experiences a total system lock-up. The only cure is a hard reboot of the PC. Some of us have had it more than ten times in one day. This does not happen if Eclipse is not running, so I can confidently say that Eclipse is the problem.

I have tried increasing the memory available to Eclipse by going into the ecplise.ini and increasing the Permsize, MaxPermSize, Xms, and Xmx. This has made no difference and everyone's PC is still locking up.

Has anyone experienced this before? I could understand maybe on one PC, but it happens on every single PC!

EDIT: Ctrl-Alt-FnX keys do not work once the PC has locked up.

EDIT: I've revisited the eclipse.ini settings and increase the memory some more. So far I haven't had a crash yet. I will use the other developers as guinea pigs, but I'm hopeful that these settings will stop the crashing.

-XX:PermSize=256m
-XX:MaxPermSize=512m
-Xms1024m
-Xmx2048m

Try upgrading the kernel to the latest version. I think this lock up is caused by the kernel bug detailed on this page https://bugs.launchpad.net/ubuntu/+source/linux/+bug/924905

I have the same issues. It is very inconvenient. I have just confirmed that killing eclipse fixes the issue for me.

However, I have found something strange in that I can still click on the stupid overlay scrollbars. It's like they have the focus of the entire system.

What seems to have fixed the issue to me was to install the gnome shell and start using gnome 3, then turn off the overlay scrollbars in the startup scripts for X. I installed gnome 3 for a separate reason and disabled the scrollbars because I find them annoying, but I do find that this has solved the problem for me. You may be able to get away with just disabling the scrollbars, information for which is readily available on google.

I have a similar problem. From time to time it happens that the complete X11 desktop freezes. I can still move the mouse but clicks on elements have no effect. In this situation I switch to the text console and kill eclipse. After I did that, everything works again. I am using a laptop with an Intel graphics chipset. So I tend to blame it on the the graphics driver. I have other computers with different graphics hardware where I haven't noticed the problem, but I don't use eclipse that often on them. On all I am using Ubuntu 11.10 64bit with gnome or unity desktop.

more a comment than an answer, but I cant add you a comment yet.

I'm kinda using the same setup: Ubuntu 11.04 64bit with Eclipse Indigo SR1 RC3 64-bit (buildid 20110909, didnt had time or need to update to a newer release yet, but RC3 is stable for me). Make sure, you have installed the 64-bit version of Eclipse.

  • OpenJDK in combination with Eclipse didnt went well for me, so I changed to java-sun jdk 1.6/7. Make sure Eclipse is not referencing to the OpenJDK installation instead of java-sun jdk.

  • I had some issues with Eclipse Indigo (pre SR1) freezing in combination with SVN Subversive/m2eclipse plugins. For me it got better with the SR1 (RC3), but still not perfect (a freeze now and then). A while later Subversive SVN had an update, and now it's stable again. In short: make sure, you have installed the newest plugin versions (use eclipse update sites, no local copies). Older versions might lead to the same problems I experienced.

  • What other plugins are you using, can you verify if your Eclipse crashes without any plugins installed?

  • Two other issues I'm aware of: with Ubuntu Karmic Koala (9.10) rendering UI elements was broken/lead to crashes as well (GTK_NATIVE_WINDOWS). Later Eclipse had problems with the native scrollbars (think it was with Ubuntu 10.10 or 11.04). I'm pretty sure, problem 1 aint an issue anymore with Eclipse Indigo + 11.04. Problem 2 I'm not sure if it was 10.10 or 11.04. But I still start my eclipse with the following script.sh and it works for me, you could give it a shot as well:

    #!/bin/bash
export LIBOVERLAY_SCROLLBAR=0
export GDK_NATIVE_WINDOWS=false
exec $(dirname $0)/eclipse "$@"

While you wait for better answers, I would definitely try a virtual machine like Virtual Box to:

  1. Try to see if I can replicate the problem in a Virtual environment, which is similar to your actual environment. This way you can see if the problem the combination of the versions of software that you're using or your physical hardware.
  2. Run Eclipse through the VM. It may not crash and will prevent you from having to do a full re-boot of the system, until you determine what the actual problem is.

This is not to resolve Eclipse problem... which might be happening because of some display issues I suspect.

Instead of hard reboot you can press keystrokes Ctrl+Alt+F1 together to reach console and there you can login to a text based terminal and kill the Eclipse process.
