OutOfMemoryError / Multiple Registration Threads in IDEA 6.0.5

Should probably mention that JDK_HOME is set to 1.6.0_04 and idea.vmoptions looks like this:
-Xms1024m
-Xmx1024m
-XX:MaxPermSize=99m
-server
-ea

Hello Russ,

After working in IDEA 6.0.5 for a few minutes, it often crashes,
consuming 100% of CPU and/or multiple OOM errors, like so:

java.lang.OutOfMemoryError: PermGen space

OS is Ubuntu, 2.6.22-14-generic #1 SMP Thu Jan 31 23:33:13 UTC 2008
x86_64 GNU/Linux

The output of kill -quit is attached. Are all those Registration
threads (94) normal? Doubt it... looks like a problem with
jetbrains.communicator.p2p.NetworkUtil maybe? The P2P makes me think
maybe it's something related to IDETalk? If so, can I disable that
component?

Yes, you can uninstall IDETalk through Settings | Plugins.

Please let me know if there's a workaround here... I'm not really able
to upgrade IntelliJ as it's a corporate license...

This problem is fixed in 7.0.x, but I don't think that any fix is available
for previous versions.
