Application Error 100 on Windows 2008 R2

Few minutes after adding a server within OME Console and enabling repeating polling of the status, we begin to have this event in the event logs:

Event Type:       Error

Event Source:   Application Error

Event Category:               (100)

Event ID:             1000

Faulting module name: ntdll.dll, version: 6.1.7601.18229, time stamp: 0x51fb164a

Then this event appears more often and after a few hours the server becomes extremely slow and we need to do a reboot.

Any idea ?

Thanks
