Mateusz Kowalski updated ASTERISK-26186:
----------------------------------------

    Description: 
Hello,

I encountered a deadlock in PJSIP module. Two backtraces available as
* http://pastebin.com/raw/kZtc5df3 (Thread 43)
* http://pastebin.com/raw/93H9qe4x (Thread 42)

Output from {{core show locks}} is empty:
{code}
tone-0058-re-1*CLI> core show locks

=======================================================================
=== 13.9.1
=== Currently Held Locks
=======================================================================
===
=== <pending> <lock#> (<file>): <lock type> <line num> <function> <lock name> <lock addr> (times locked)
===
=======================================================================
{code}

Any packets arriving to the machine on port 5060 are left without any response. They are not visible in Asterisk console even with {{pjsip set logger on}}

Output from netstat shows big RX queue:
{code}
udp   214912      0 0.0.0.0:5060            0.0.0.0:*                           46787/asterisk
{code}

Initially I reported issue on #asterisk but later on got redirected to open a ticket in here.

Thanks for any help,
Mateusz
