9886 - 100% cpu usage and system freeze after a few hours

I have a 64-bit linux system. I keep having this issue where after a couple of hours of running, idea freezes up and cpu goes to 100%. If I don't kill idea in time, my system soon becomes completely unresponsive.

At first I thought it was a problem with my setup (Ubuntu jaunty 64-bit), so I switched to a completely different computer, also 64-bit but different linux distro (Arch 64-bit), and I'm having the same freakin problem.

I have a dual quad xeon with 4GB of ram so this should not be happening.

JDK 1.6_14 on both systems.

Any ideas? Extremely frustrating...

I am using 8.1.3 on ubuntu jaunty without problems. though I use the 32-bit linux version on a 64-bit.
did you check out the idea.vm settings (increasing heap)?

Yeah I've messed around with vmoptions a bunch, because I also noticed steadily increasing memory usage even while idle.

This all started happening when I switched to 64-bit and upgraded to 9886. My guess it's probably something to do with switching to 64-bit?

Hello James,

Most likely you should increase the -XX:MaxPermSize value in idea.vmoptions.
The defaults assume a 32-bit SDK, and a 64-bit one requires more PermGen
space.

couple of hours of running, idea freezes up and cpu goes to 100%. If I
don't kill idea in time, my system soon becomes completely
unresponsive.
