imon.dll, RPC, and svchost.exe

Using NOD32, WinXP SP2

Occasionally I get these errors popping up in the Event Viewer. I leave my PC on overnight and it seems imon.dll is faulting svchost.exe and causing an RPC problem, which forces a reboot.


Application log:

Faulting application svchost.exe, version 5.1.2600.2180, faulting module imon.dll, version 2.50.25.0, fault address 0x0000b1eb.

Any thoughts on what might be causing this?

 

I had this exact problem, and I found it was related to Diskeeper not playing nice with NOD32.

I got rid of Diskeeper and changed to O&O defragmenter and the problem went away.
