Hi All This sounds just like a problem I have had and still investigating having moved to 16.9 using chan_sip. I am still trying to repeat the problem it looks from debug that the issue is either voicemail of call transfer but I cant consistently repeat it. Voicemail is using ODBC and I just imported the data from the old system into the new database. Nick - if you have any more info I would be grateful TIA Paddy _____

The voicemail is held in MYSQL as well (via ODBC). And we found when attempting to playback a customers voicemail unavail greeting is when the deadlock would occur (Immediately, every time. Throwing the same "task processors" errors, And making pjsip completely unresponsive). We had imported a number of greetings from a legacy asterisk system and the vast majority of them worked. When we deleted the row containing the customers unavail greeting (making asterisk revert to read the mailbox number) all issues went away. If we re-record the customers unavail greeting it works fine and the problem doesn't reoccur. This was one out of ~250 voicemails imported. Since then we've done a few more migrations and they've all gone smooth with the exception of the most recent one. ~50% of the imported greetings have caused asterisk to deadlock. We've been checking them now at time of migration. What I can't figure out is what it doesn't like about the greeting. It was on a previous asterisk system working fine. The row looks identical to a working one. The only thing I can guess is something about the blob for the recording goes wrong. It would be nice if asterisk handled that more gracefully. I post this mostly just for internet history. To hopefully help the next guy out who has this same issue.

Does PJSIP handle database access the same way Chan_sip did? We had a number of boxes running chan_sip referencing the same mysql server without issue. We're going to attempt to get a backtrace on the next occurance. We're also going to run a local copy of the database on the same physical asterisk instance and have the system reference it. Just to "throw everything at the wall". It uses the same underlying API and layer. It can do more frequent database access though due to queries and because PJSIP is multithreaded. -- Joshua C.
