I'm regularly seeing Out of Memory errors when I fire up my IDEA with my language plugin installed and then go to the settings dialog (this is on a Macbook Pro running OS X 10.5.6 with 4GB of physical RAM).
Naturally, I assumed that I was doing something stupid, but - starngely - I was able to stop the Out of Memory errors from happening by disabling the IDETalk plugin. (?!?) I haven't yet tried to see if disabling any other plugins has the same effect.
I don't think my JVM memory settings are an issue, as I've bumped my min/max seetings to 512MB/1024MB.
Does this sound at all familiar to anyone?
