First of all - this has only happened once, but since I don't like the idea of accepting problems I'll report it here :)

This was a very simple call, with more or less default dialplan (no external applications involved, just a simple bridge command). It's an incoming call from 9029 (from an Asterisk box), that is bridged to another gateway (on the same sofia profile), to destination 7026 (on a Lync server). What makes this call a bit different then other calls is that the call is hungup just at the same time it's answered, so I'm guessing there might be a race somewhere, that causes a read lock not to be released as it should.

Channel 7026 stucks and waits for all locks to be released, but that never happens.

This has not been reproduced on latest GIT, but it was just a couple of days old - and I can't see any changes since then that should make any difference.

I've tried to check through the code, but I couldn't really find anything that would cause this - and I've never been very deep inside mod_sofia code...
