Lock-up in editor (keyboard doesn't respond)

Recently I started to experience an ocasional lock-up of keyboard in IDE editor. It possible to make editing only by mouse (even text selection with SHIFT key). Closing and reopening of a project, reducing highlight syntax leveldoesn't solves a problem.
This behavior is very annoying. I have to save changes and restart an IDE every 2-5 minutes!

Both RubyMine versions 3.0.1 and 3.1.1 with same problem. Java Sun 1.6.0_24 is used as Java VM. I suspect, recent updates of Ubuntu 10.04 (yesterday) caused such behavior.


Help me fix this issue, please.

I cannot provide thread dump because IDE itself responds on mouse events, so no files like threadDumps-xxx been created.
Keyboard keep working with other applications as regular.

RubyMine/Java eats up to 450-500 MB of RAM of maximum 640MB allowed. Only about 40% of RAM is used by all processes.

I use 32-bit kernel with physical address extension (PAE) for 4 GB RAM.
$ uname -r
2.6.32-31-generic-pae

I tried rubymine.vmoptions with default options of virtual memory and these - same effect:
-Xms32m
-Xmx640m
-XX:MaxPermSize=150m
-Xverify:none
-XX:+UseParallelGC
-ea
-Dsun.java2d.opengl=true

Can you reproduce such behavior in your environment?

Usually I refrain from experiments with my working environment, so a question "what's going on?" remains be opened.

It seems clipboard operation causes lock-up.
