I work remotely, and use a VPN where I have typical ping times to our CVS server in the 180ms - 240ms time range.

When IJ decides to do a cvs rlog operation to find the incoming changes, I see my CPU usage go up (50-75%) and IJ itself becomes very slow to respond.

Also during these operations, I've seen some OutOfMemoryErrors, though I cannot guarantee that the two are related, just that I have not seen IJ run out of memory in other situations.

FWIW, my idea.exe.vmoptions has the following:
-Xms32m
-Xmx192m
-XX:MaxPermSize=120m
-ea

Just ran into this issue when I'm local (ping times to our CVS server are < 5ms)... And since I was doing nothing else, I'm fairly sure that the OOM was caused by this issue. I've attached my idea.log file.

The OOM at the end of the file occurred while the cvs rlog was happening. Nothing else was going on (I was not editing any code or opening/closing any files, etc...)
