             Summary: Asterisk deadlock when using confbridge

                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-25871
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
    Affects Versions: 13.7.2
         Environment: CPU Family:Intel Core i3 Sandy Bridge
Operating System:	Linux Ubuntu 14.04 LTS
Architecture: 64-bit
RAM: 8 GB
Disk Mode: Standalone (No RAID, 1-4 Disks)
RAID Mode:	None (2-4 Disks)
1st Disk:	500 GB HDD
            Reporter: Val
            Severity: Critical


We use asterisk to mix WEBRTC streams and encounter random deadlocks.
When there are 2 or more participants in a conference (the number is not relevant, the deadlock may occur when there are only 2 participants and work fine when there are 140, and sometimes vice versa) after a random time 1 CPU goes 100% and all calls are dropped.

The console doesn't show something special:

by the way we get a lot of these:
[Mar 29 18:15:33] DEBUG[15106]: acl.c:958 ast_find_ourip: Not an IPv4 nor IPv6 address, cannot get port.

We have compiled our asterisk with DEBUG_THREADS and DONT_OPTIMIZE.
