EventID 2020

We have a Windows 2003 SP2 server that occasionally generates EventID 2020.  Around the same time it starts generating many Event 7011 errors per hour and hangs when we attempt to reboot the system.  Both issues seem to be related to resources on the system.  I found the following online and am wondering if anyone has been able to correct the 2020 errors following these instructions?  I ask because our PagePoolSize is also set to 192 MB and am considering doing the same.

We found that a possible cause for this problem, which eventually ended up with one of our main Terminal Servers crashing was due to falsely detected problems with the registry size causing the system to think that it did not have enough resources to update the users roaming profiles.
It appeared that somehow the PagedPoolSize registry setting had been set to 192 MB, the maximum that it could be according to Microsoft. Setting it back to zero allows the system to decide how much it needs by itself.

A 2020 error if I remember correctly is running out of memory.
Check for memory leaks and what are the settings in the boot.ini file, is the a /3GB?
Correct 2020 is paged pool exhaustion. This is generally fairly easily dealt with. Steps below:

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.
