SAPOsCol running but not working (shared memory not available)

Dear Forum,

We have just set new passwords for SAP AD users (incl SAPService<SID> and <SID>adm), after this restarted SAP instances and servers / clusters). Everything came up well and all services, incl SAPOsCol started up automatically with the new passwords.

Everything works fine - only this morning i wanted to have a look in ST06 and the program tells me "SAPOSCOL not running? (shared memory not available).

The service is running tho, would a restart of the service do any difference, and is there any possibility that a restart of the service on a live and running system would force a system restart? (i couldnt think of any, but I hate restarting services on a live running production system).

Would it be an option to stop/start the collector from ST06?

Thanks in advance,

Kind regards,

I suggest that the "cold" reboot of server solves the shared memory problem , since it is your production server you need downtime.
