             Summary: Asterisk Crash - astobj2.c: FRACK!, Failed assertion bad magic number 0x0 for object 0x7fc9f402d088

             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Addons/General
    Affects Versions: 13.13.1, 13.11.2
         Environment: - Ubuntu 14.04
- HP ProLiant DL380 Gen G7
- Digium, Inc. Wildcard TE820 octal-span T1/E1/J1 card 3.3V (PCI-Express) (rev 02)

Under low or high load the server starts to get high CPU usage and call quality drops until the box becomes unusable. It's a production server so hard to run traces on as usually it occurs when there are a large amount of calls.

I compiled in the DEBUG options from the troubleshooting guide and have attached a trace. The server had not fully crashed by this point but asterisk process was filling approximately 8 cores on the server at 100%. The only fix is a core restart.

I can't recreate it but it happens almost every day, to alleviate the issue a graceful restart is scheduled each day during a known low call period, the box is required 24/7.

Upgraded to 13.13.1 as an attempt to fix but still occurring.
