Monitoring seems to be stopped for windows servers (wmi)

 
Hello,
 
My monitoring stopped working for windows servers
 
In the device summary view I cannot see the perf grpahs (see the attached images). The same device summary was ok  till now
 
A line of this sort is appearing in a log file called stderrxxx.txt

If I reboot the opmanager probe server it works again but temporarily....
 
Please can you help me troubleshoot this
 
Regards
