---------------------------------------------------------------

Just an update;  We believe that we may have isolated this issue.  We have a Polycom SoundPoint VVX310 unit which is located in a remote office... this phone is in such a position where it is directly attached to a TP-Link Wireless bridge (no ethernet connection is available in the room with the phone).  Once this Phone is disconnected the crashes have stopped.  We believe that somehow the TP-Link bridge is causing malformed SIP packets/requests and causing the core dump within PJSIP.  My understanding is that this is also causing the phone to reboot/crash.  We are going on 3 hours with no crash within Asterisk after disconnecting the phone which seems like a new record.  We are going to test for 24 hours and I will comment back then.

Potentially Problematic Network Setup is as follows:

Asterisk < E(NAT) > Router < > Internet Backbone < > Router < W(NAT) > TP Link Bridge < E > Polycom VVX310 Phone

NAT = NAT Translation
E = Ethernet Connection
W = Wireless Connection

>          Issue Type: Bug
>      Security Level: None
>    Affects Versions: 13.11.2
>         Environment: Fresh installation of FreePBX Distro 10.13.66-64-bit, Sangoma 4-Port FXO PCI Card, Dell PowerEdge T20

> Asterisk 13.11.2 will randomly crash/core dump, and restart.  Unfortunately, I have not been able to find a pattern to this behavior.  Crashes seem to happen at least 1-2 times per hour
> Please let me know if you require and more information.
