[BlueOnyx:20031] 5209R Sendmail hanging gripe

[Chris Gebhardt - VIRTBIZ Internet]

Every so often, and usually in the early morning, we will find our 5209R
boxes with hung Sendmail.    Typically if it happens on one, it's
happening on the others as well.  I wonder if anyone else has had this
happen?

Sendmail will simply stop responding, so if I quiz systemctl as to its
status:

* sendmail.service - Sendmail Mail Transport Agent
   Loaded: loaded (/usr/lib/systemd/system/sendmail.service; enabled;
vendor preset: disabled)
   Active: inactive (dead) since Wed 2016-08-31 06:06:43 CDT; 1h 20min ago
 Main PID: 17176 (code=exited, status=0/SUCCESS)


Well gosh, that's helpful.  Thanks a lot to Active Monitor for picking
up on that and restarting the service.  <rolleyes>

I'd say that it often will correlate to a YUM update (as is the case
this morning) but that's not ALWAYS the case.

Has anyone else also run into this?   And if so, ideas for getting the
service to restart on its own?  Surely if systemctl knows it's down,
Active Monitor should be able to pick up on it as well?    Or maybe I'll
have to craft a script to kick the service if Nagios detects it's down.
 That just seems like a kludge...
