Asterisk then restarted automatically via monit daemon:

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.
