[SR-Users] Random Proxy Crash, Restarted OK Anything Here For Concern?

[JR Richardson]

Hi All,

I have a basic proxy up and running for over 6 months without issue,
had a random crash, not sure why. Restarted kamailio process and it's
working as expected. Any clue is the log to indicate what might have
happened?

RTPProxy also running on the server was not affected.

Yes, I know it's an older version but I prefer not to upgrade unless
absolutely necessary. I'm sure this was a random event, not too
concerned but since it is a production server, I'm obligated to
investigate.

Thanks.
