if I start the OES2SP1 server, everything is ok.

After a few days, the update icon of ZMD disappears
and "rug sl" does not show any output.

The output of "rczmd status" is "running"
but the output of "rczmd stop" is "failed".
The output of "rczmd restart" ist "failed" and then "done"

If I restart the server, everything is ok again:
"rug sl" is correct, the ZMD icon is displayed und
"rczmd restart" is also correct.

Any ideas?
