I am kind of new to running java apps so I am not sure exactly how to troubleshoot this. What happens is that the IDE opens and loads the project successfully, and the first couple of interactions with it work fine, but soon enough the UI starts to freeze and ultimately the java process ends up needing to be killed after hanging at 100% cpu usage. I can't point to one root cause for the freeze, but it seems to be particularly triggered by things like opening windows and switching focus. For what it's worth, system monitor shows the java process as sleeping at 24% CPU with a waiting channel value of futuex_wait. I chalk up the discrepancy between that and the 100% number I get from top to my general ignorance of the environment.
I attached the contents of .rubymine10\system\log. Let me know if there's anything else.
by the way, rubymine is fantastic so far. i started out with it on windows and was impressed that it was able to get a functional rails environment up and running so easily. unfortunately the main reason i've run into this issue is because there are just too many gems that you can't use on windows.
