             Summary: IAX2 Freezes asterisk
                 Key: ASTERISK-26095
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-26095
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_iax2
    Affects Versions: 13.7.1, 12.5.1
         Environment: Ubuntu 14.04.1 LTS (GNU/Linux 3.13.0-32-generic x86_64)
wcte13xp+    d161:800a Wildcard TE131/TE133
            Reporter: Ben Crox


Asterisk ran out of threads during some of iax2 to dahdi calls.
1 out of 20+ calls may end in such issue.

Meanwhile, there are merely 6k calls per month, 400 call from iax2 to dadhi for the box. 20 hangs per month shall be considered quite severe. 
No freepbx, no hylafax, just asterisk + libpri + dahdi + AMI applications

When frozen, 1 of cpu might have 100% usage, memory usage is just 20% ~ 40%, harddisks, network, NAS are all fine.

CLI is accessible, but no new log / verbose / debug messages. 
Core show locks reveals huge amount of MUTEX lock by chan_iax2.so .
fd limit is not yet a problem for any other new process.  

core restart does not work ( and may held CLI ) 
service asterisk restart does not work.
Can only hard KILL safe_asterisk or reboot the box.


 ( version 13.1-cert7  )
