Server reacts only slowly / No jobs are processed

Description
The Windows server only very slowly reacts to PLOSSYS commands and it is possible that no jobs are being processed. When running a „sysstatus“ command in a SEAL shell, several processes are displayed as busy and not reacting.

Cause
Presumable this is caused by a problem with the WMI (https://en.wikipedia.org/wiki/Windows_Management_Instrumentation ).
To check if there is a problem with the WMI, please open a SEAL Shell and execute the command „wmic process“. If you do not see an output after 2-3 seconds, there is a problem with the WMI.

Solution
To reset the WMI repository, please execute the following command in the SEAL shell: Winmgmt /resetrepository
If this has no success, please reboot the server completely.

If both did not help, you can also rename the file ..\tools\perl\bin_winnt5\site\lib\DBD\WMI.pm (for example to WMI.pm_OFF), then ps –ef will be used. The change is active immediately.
