How reproducible:

Consistently but not at will.

Steps to Reproduce:

1. Start jabber services
2. Wait 1 or 2 days
3. Observe that c2s has been killed

Actual results:

Process /usr/bin/c2s was killed by signal 6 (SIGABRT)

Expected results:

c2s not being killed

Additional info:

This particular customer has a relatively high number of OSAD clients (~5000+) and is having load related issues among other things. Would be helpful that c2s does not die unexpectedly.

I did find a somewhat similar backtrace from here:

due to the customer escalation, I set the 'customer escalation' flag.

Comment 19 Tomas Lestach 2018-04-10 08:26:52 UTC
We have re-reviewed this bug, as part of an ongoing effort to improve Satellite/Proxy feature and bug updates, review and backlog.

This bug has currently no open customer cases. While this bug may still valid, we do not see it being implemented prior to the EOL of the Satellite 5.x product. As such, this is being CLOSED DEFERRED.
