Since we are on the paged pool topic, has anyone got the link to how to set perfmon to trend a leaky app or some other way to watch and log the trend over a period of a couple days or so?

There was a bug in the MS library they are all linked to. A lot of things can happen aside from that symptom below when you run out of nonpaged pool. A good indicator is if you see the SRV events (2019 or 202, I forget which one) saying you’re out. Machines can hang, apps can stop working, etc. Thanks, Brian Desmond [email protected] c - 312.731.3132 Active Directory, 4th Ed- http://www.briandesmond.com/ad4/ Microsoft MVP - https://mvp.support.microsoft.com/profile/Brian From:Ziots, Edward [mailto:[email protected]] Sent: Tuesday, June 30, 2009 6:34 AM To: NT System Admin Issues Subject: For those that use multipathing solutions with your servers NON Paged memory pool leak All, http://seer.entsupport.symantec.com/docs/317378.htm http://blogs.technet.com/andym/archive/2008/12/04/powerpath-5-2-and-mpio-causing-npp-leak.aspx The culprit in EMC land is the 5.2 and 5.2 SP1 PowerPath Drivers ( MPIO.sys of 1.22.3790.2358) and the EMCMPIO.sys of 5.2.1.6 (5.2 SP1) The fix: Move up to EMC multipath drivers Version 5.3 which will load Microsoft’s MPIO.sys updated to 1.23.3790.2451 which seems for the time being to address the Non-Page Memory Pool leak, this was driving one of my Exchange 2003 SP2 2-node clusters insane over the last few months, it was discovered if the NON-Paged Memory counter you see on the Task manager gets about 106-108MB for a X86 32bit system, the http service for the Exchange Cluster will fail, and cause the Exchange group to fail because the resource is marked to affect the group.
