Sometimes IDEA seems to get stuck when compiling my straightforward 73 line Scala file, and takes something more than 20 minutes to complete. Other times, it takes just a couple seconds. Killing IDEA and restarting it dosn't seem to help - it just goes back to where it was. Letting it run to completion doesn't help. I let it finish, commented out a couple lines, and the next build got stuck, too.
The machine has more than enough power to make quick work of the task - 2 dual-core opterons, 4Gb of ram, and no one else using the machine. It is running Debian 6, and I am trying out the IDEA community edition that I just downloaded today. I rebuilt the machine last week, so all the software is quite new. Any thoughts on why IDEA would be unusable?
