I can easily change this write to be nonblocking and just retry later instead of hanging, but there is still a bug if director never reads it..
This should fix it: http://hg.dovecot.org/dovecot-2.0/rev/510b627687f8
So far so good! I upgraded the directors and switched the webmail system back over a few hours ago and it has yet to get stuck. So glad it was something fairly easy to fix, I was beginning to despair that it was an imapproxy problem that I'd have to track down and fix myself.
Makes sense that it was the notify socket, I had noticed that the 'doveadm director status' user numbers would drop off significantly after it had been running for a while, but I didn't know what to correlate that too.
