Failing timer job SharePoint Worker Process Group Update

Hi,

On the farm of my customer on my application servers I see the timer job "SharePoint Worker Process Group Update" stuck in a retry state. On my 4 front end servers they are succeeded on my 3 application server they are stuck on retry. I see eventlog criticals

The Execute method of job definition Microsoft.SharePoint.Administration.SPUpdateWorkerProcessGroup (ID 9b4d28e2-5d0f-4748-a844-e19a07f425a6) threw an exception. More information is included below.

1387

Any ideas? On all the servers all rigths are the same

regards

Danny
