I do have the core dump file if requested I can upload it as well.

Forgot the actual syslog segfault message. It is:

Dec  9 12:37:18 voip01 kernel: asterisk[23929]: segfault at 0000000001120000 rip 0000002a96a99dc4 rsp 0000000043ca2010 error 4

As noted, I do also have the core dump, but it's gzipped to 5.4 meg - too large for your 2 meg limit on file uploads.

Please follow the instructions of backtrace.txt in the doc directory to get a backtrace using your core dump and attach it to this issue.

This backtrace is very familiar and has been mostly fixed in current 1.4 code. The first step you need to follow is to update to the latest 1.4 code. It appears there was still a potentially uncaught case of this crash occurring, and it is being tracked on issue ASTERISK-13507. I am closing this issue since it is a duplicate of known issues.
