IntelliJ freezing

Hi, I have a vague problem - my IntelliJ keeps freezing up on me.  On 8.0, it started happening after working for 2 minutes, so I'd kill it, restart, and repeat.  I upgraded to 8.1 and I managed to work 1/2 a day without it happening, but now it's started again.  Once, I got the following stack trace - this was on 8.0.  I wish I had more more specific to offer, but I haven't made any recent changes, and I can't narrow it down to any particular action - it freezes in the middle of typing.  Any ideas?  Thanks
