SBS 2003 freezing randomly

Hi, my SBS 2003 box will freeze randomly every couple or days or so.

I have inspected the System Event Log and found this.

At 6:43 PM there is an Error:
The server was unable to allocate from the system paged pool because the pool was empty.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

Then at 7:11 is happens again:
The server was unable to allocate from the system paged pool because the pool was empty.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

Then from 7:13, every 30seconds the same error will occur and will not stop until the server is manually reset using the reset switch:
An I/O operation initiated by the Registry failed unrecoverably. The Registry could not read in, or write out, or flush, one of the files that contain the system's image of the Registry.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

Can anyone tell me whats going on?

We really need to capture Poolmon data when this is happening. There is a set of scripts that will do logging for us over time. I put a copy at http://bdesmond01.dyndns.org/poolmon3vbsperf.zip. Extract them somewhere (e.g. c:\poolmon), run _LogPool-as-a-service and leave it until this happens again. We'll need the resulting data (in Poolmon-Output) at that point.

Thanks,

I think you have an application that is leaking memory. Non paged pool  is being allocated but not being freed back up

Check this
http://support.microsoft.com/kb/133384

it might be a good idea to run an application on poolmon and see what handle and proccess ID are where non paged bytes allocated is increasing at a hugher rate than non paged bytes freed.

You may need to run it over a period of time to get an accurate idea of what is leaking
