IDEA hangs and does not recover on my my machine from time to time. No error messages, nothing in the logs. It only appears to happen when there are one or more Run/Debug processes, although those processes are not affected by the hang.
I have tried killing the processes using Task Manager, but it does not affect the hanged IDEA. I have tried running the processes using the YourKit profiler plugin, but there were no significant problems shown.
Recent thread dump attached, I will add more as they come.
