Question

I just upgraded my Ubuntu to 14.04 a few days ago and in the process switched from 32 to 64 bits. Ever since, Eclipse has gotten really unstable. After having run for a few minu

Answer 1

Had the same problem and Lars' article solved it for me. Seems to be an issue with SWT and GTK3.

Answer 2

Had the same problem for a few days. Added the following line in the end of eclipse.ini and it solved for me:

-Dorg.eclipse.swt.browser.DefaultType=mozilla

Answer 3

Update

https://bugs.eclipse.org/bugs/show_bug.cgi?id=404776

There are a couple of workarounds in the comment thread. Folowing to the comment 22, I've added this to my eclipse.ini.

-Dorg.eclipse.swt.browser.UseWebKitGTK=true
-Dorg.eclipse.swt.browser.XULRunnerPath=/opt/xulrunner/1.8.0.1/xulrunner

I had installed xulrunner into this directory for some reason, don't know why exactly this version.

This is not really an answer but I need the space for pasting in the data of my system config. Just for comparison, hope it helps.

I have this same problem when I work on PHP projects, and it annoys me too: Sometimes eclipse 4.3 crashes on Ubuntu 14.04 64-bit when I hit the keystroke combination for content assist / autocompletion (Shift+Space). Happened on 13.10 as well.

I have no clue what migtht cause the error. However, I noticed that my system has very little free memory. Moreover the JAVA_HOME variable pointed to an older path of the JRE.

Maybe Alt-F2 and typing unity --replace & helps. Alternatively maybe you can send a HUP signal to com?piz

Answer 4

I faced the same problem and still face it. though the frequency is somewhat become lesser after I increased JVM size in the file "eclipse.ini" just change these lines:

-XX:MaxPermSize=256m
-Xms256m
-Xmx2048m

and start Eclipse from terminal :~/Desktop/eclipse$ ./eclipse

It will decrease the frquency of freezing if not resolve it completely. Hope it helps.
