While struggling with Applicationn hung problems I have discovered that the
following error has frequently been reported (some 400 times) on my system
since June 11, 2008:

"Failed to create restore point on volume (Process =
C:\Windows\system32\rundll32.exe /d srrstr.dll,ExecuteScheduledSPPCreation;
Descripton = Scheduled Checkpoint; Hr = 0x80070422)."

(The parameters have varied)

I have followed the various tracks Event Viewer suggestions but am no more
the wiser.

Can somebody enlighten me on what is going on and what I can do about it?

(There is no apparent correlation between this error events and the
Applicaction hung events)
