             Summary: Asterisk hung channels
                 Key: ASTERISK-26652
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-26652
             Project: Asterisk
          Issue Type: Information Request
      Security Level: None
    Affects Versions: 11.21.2
         Environment: Centos 6.6. Final running Linux Kernel 2.6.32
            Reporter: Andrew van Niekerk


We run several hosted PBX at a data center with remote extensions. Most are running fine but there are several of them that get stuck/ghost channels. The only way to fix it is to restart Asterisk otherwise Asterisk crashes eventually once you reach a few thousands calls. Here is an example of when it starts:

54 active calls
41.221.0.33      4c6765c32fd  28:08:35 0000000000  0000000000 ( 0.00%) 0.0000 0000000000  0000000000 ( 0.00%) 0.0000
41.221.0.33      628c3c2b69d  03:49:53 0000000000  0000000000 ( 0.00%) 0.0000 0000000000  0000000000 ( 0.00%) 0.0000
77 active SIP channels


I have tried:

1) Increasing max DB connections
2) Increasing max open files
3) Adjusting jitter buffers
4) Added SSD drives to system
5) Repaired MySQL DB
6) Rebooting
