I run offlineimap in a cronjob every 5 minutes, unless it is already
running. Every few days, I find the process hung. It doesn't respond to
normal kill messages, except but kill -9. So I cloned the git repo, ran
it from there, and next time it happened, I attached gdb and did a
trace.  I didn't have much time, and printed a few pages of the call
stack, assumed there was a repeating pattern then quit. I'm going to
have to add some logic to kill -9 offlineimap.

My os is ubuntu 14.04.

The stack trace is attached.

Any idea whats going on? Is this a bug?
