Description:I recently upgraded to asterisk 1.8.6.0 and applied the queuelog patch. Currently I am experiencing a number of lockups throughout the day. I finally recompiled with Don't optimize and debug threads so I could get a bt for the tracker. There was no core dump. The log shows this before the lockup:

Also I just noticed that the timeout for parked calls is going into negative seconds.

then some seconds later

This is a 2nd backtrace from a lockup that occurred slightly after restarting asterisk.

It looks like you're using res_timing_pthread -- that is likely the problem you're having. If using 1.8.7.0-rc1 or later, you can use res_timing_timerfd, otherwise, you'll need to use res_timing_dahdi.

we don't use dadhi on this machine.

Closing this as a known issue.

That is not the issue. After doing a noload on res_timing_pthread, there is no effect. The system is locking up on reload every 5 minutes now.

Also queue agents are reporting receiving multiple calls at once.

Can see a problem not sure its timing fd related but will need output of core show locks and do try 1.8.7-rc2
