Messenger failed

Hi guys,

strange problem today - our messenger Service don't work propably so we
can't login to messenger.

Status says:

gwm-nmma.service - GroupWise Messenger Messaging Agent (NMMA)
Nov 04 10:02:08 srv-raas-13 systemd[1]: Starting GroupWise Messenger Messaging Agent (NMMA)...
Nov 04 10:02:08 srv-raas-13 systemd[1]: gwm-nmma.service: PID file /var/opt/novell/messenger/temp/nmma.pid not readable (yet?) after start:...directory
Nov 04 10:02:14 srv-raas-13 systemd[1]: Started GroupWise Messenger Messaging Agent (NMMA).
Hint: Some lines were ellipsized, use -l to show in full.

I tryed many things - Restart Service, Restart gw Services - Restart Server - Nothing works.
When i Restart the nmma Service i'm able to connect to the messenger but after 4 seconds he kicks me off and says "Error: GroupWise Maintenance has expired; terminating..."

After a login try the nmma service Status says

I guess ist because of PID file /var/opt/novell/messenger/temp/nmma.pid not readable but
i dont know how i could fix that.

Any ideas?
