Description

I had tried to start Couchbase Server but it was just chewing on CPU without coming up, so I tried to stop it. The problem report dialog came up with the attached.

I don't know that this would be easy to reproduce, but it could point to some un-handled error.

Looks like -invalidate was sent to a dealloced object. Likely an NSTimer refcounting issue.

This is a race condition that can occur if the server task takes long enough to terminate. The fix is very simple (one line to nil out a reference to a timer object that's about to go away.)
