Cluster failing on the HTTP resource? Non-Paged pool memory high?

  • Article

Is your cluster failing over?

Is it the HTTP resource going first? This seems the first resource to fail if NPP goes to a critical level.

Things to check include:

Is the TCPChimney in place (See my other blog post :) https://blogs.technet.com/andym/archive/2008/03/13/exchange-2003-2007-windows-2003-sp2-high-non-paged-pool-memory.aspx )

Check System Pages is set appropriatey (BPA will tell you this)

Is HeapDeCommitFreeBlockThreashold set appropriately? (BPA tells you this too)

Are you using the standard VGA driver? If not why not!

Have you upgraded any drivers recentlt? These could be suspect.

Get a perfmon, establish when its leaking, is a certain process taking a chunk of memory?

If in doubt we have tools to monitor the tags that take up the PP and nonPP memory, log a case!
