I have noticed that all of my EAP's since 214 (most history I did maintain) all have at least 1 core file. 413 has crashed 2-3 times in the few hours it has been installed (each time while right-clicking on a method). I also have a thread about how 289 used to crash when idle also. This is not normal behavior for previous Idea versions in the same environment. I have attached the core files. This is on Ubuntu 8.04 using JDK 6u20x64.
