[Samba] MIT Kerberos suddenly stopping

Hello,

I'm using samba 4.7.3 to run an AD and I'm currently having issues with
the MIT kerberos because it stops some time after starting (and
apparently working correctly) without logging nothing out of the
ordinary.

My setup has 2 DC: one in an ubuntu 12.04 with version 4.1.9 (which
we're migrating from) and the one I mentioned in CentOS 7 (which will
be the only DC in the future). 

Can someone help me troubleshoot the issue or tell me if it's a known
bug?

Best regards,

--

[Samba] MIT Kerberos suddenly stopping

Hello,

I was able to get a dump from strace when the daemon shutdown, in case
it's helpful. Does anyone help had the same problem?
