      Security Level: None
    Affects Versions: 13.15.0
         Environment: Cettos 6.8 Final
            Reporter: Ryan Smith

Asterisk/PJSIP simply stops processing any further SIP packets. Incoming options "ping" packets from proxy see a task-processor limit error related to pjsip/distributor (live clients have been redirected by fail over by time of requesting a core dump) Unfortunately debug log files have been deleted until the next occurrence.

Asterisk will often seq fault on requesting the core dump.
