Mknotifyd always getting killed when stopping omd

Hi,

no matter what, mknotifyd will always be killed.

OMD[monitoring01]:~$ omd stop
Removing Crontab...OK
Stopping xinetd...OK
Stopping redis...killing 3073903...OK
Stopping dcd...killing 3073891....OK
Stopping apache...killing 3073806.................OK
Stopping cmc...killing 3073704.....OK
Stopping rrdcached...waiting for termination...OK
Stopping mknotifyd...killing 3073682...............................................................sending SIGKILL...sending SIGKILL.../omd/sites/monitoring01/etc/rc.d/20-mknotifyd: line 40: kill: (3073682) - No such process
OK
Stopping liveproxyd...killing 3073666....OK
Stopping mkeventd...killing 3073656...OK
Stopping 1 remaining site processes...OK

After that, theres always a new file in var/check_mk/notify/corrupted/
This is only happening on the second instance within a 2 instance cluster.

This instance is running CentOS 8 whereas the master instance is running CentOS 7, if that matters

How would I debug this?

Cheers

Before you stop your instance is there something in the queue of the mknotifyd?

No theres nothing in the queue.
Also all services are running fine

OMD[monitoring01]:~$ omd status
mkeventd:       running
liveproxyd:     running
mknotifyd:      running
rrdcached:      running
cmc:            running
apache:         running
dcd:            running
redis:          running
xinetd:         running
crontab:        running
-----------------------
Overall state:  running

Now I deleted all files in var/check_mk/notify/corrupted/* and var/check_mk/notify/spool/*
In ‘spool’ there where around 3k files. Now mknotifyd is able to be restart without killing it.

OK, that didn’t help.
spool DIR is filling up with notifications, nothing gets send. I can send mails though from the host itself.

If your system cannot sent the notifications, you should also have error messages in your “~/var/log” folder.
