I feel like I'm crying "wolf!", so let's put this "bug" on ice for a moment: my previous hang issues were a showstopper for me and I got really busy at work. I migrated my email out of aox because I didn't have time to debug further.
Last night I saw that a release was likely approaching and I'm the port maintainer on FreeBSD, so I fired 3.1.3 up with a clean database and started syncing my email with imapsync. I thought I saw the old stall/hang I used to hit -- no CPU consumption on the aox/postgres side, client doesn't appear to be doing anything but waiting/locked indefinitely. Built git head -- thought I saw the same thing. Left it running all night in that tmux session, woke up this morning and saw mails moving..... I'm not connecting with TLS right now, and previously I was able to reproduce it both with and without. This heisenbug might have gone away, but my environment is slightly different from January but I know there hasn't been that much code change since earlier in the year... Let me get all my mail in it and spend a few days reading it from a few clients and see if I can trigger it again. It would usually happen within an hour or two of service uptime and the only fix was to restart my client or restart the aox service. Funny how when I start playing with aox again I long for my email to be back in it (it's so damn fast!).
