MSCS Cluster fail over issue!!!

[Former Member]

Hi,

We have our BW production server on MSCS. The issue we are facing now is, when the CI is down it does not fail over the other node, rather it comes up automatically after sometime. In the event log it is writing the following:

<b>Type of event: Error

Event source: Srv

Event category: It is not (NA)

Event ID: 2019

Date: 2006/12/25

Time: 23:21: 59

User: N/A

Computer: SAPN

Explanation:

Because the pool was empty, the server was not able to be allocated from non-page pool of the

system.</b>

Also it says cluster service SAPLOC and SAPMNT not available. It goes to offline and then back to online. We contacted the vendor and they suggested to use an utility called poolmon.exe. They also gave a batch file entries to use.

<b>@echo off

for /f "tokens=1-3 delims=/ " %%a in ('date /t') do set date=%%a%%b%%c

for /f "tokens=1-3 delims=: " %%a in ('time /t') do set time=%%a%%b%%c

rem set filename=poolsnap-%date%-%time%.log

poolmon -r -n poolsnap-%date%-%time%.log</b>

See http://support.microsoft.com/kb/177415/.

Not sure if this utility is safe to use or what the issue is, etc. Have anyone faced similar issue.

Any help would be appreciated.

Thanks & Regards,

it looks like you are still on 32 Bit - needless to mention that 64 Bit would help here...

there are two pools: paged pool and nonpaged pool which can be effected, typically nonpaged pool is causing bigger troubles.

pool leaks are serious problems caused by often kernel mode routines in drivers etc. We have seen problems where a printerdriver, anti virus software, scsi card driver was causing a problem.

Also windows filesystem compression needs a lot of pool resources and specially when simultaniously opening a lot of large compressed files may empty your pool.

poolmon.exe is safe to use and only used to find out which program (tag) is consuming how much pool.

by the way - is this issue happening on Windows 2000 or Windows 2003?

Hi Peter,

Thanks a bunch for your response. The issue is in Windows 2003 server.

But from poolmon how to determine the issue? It gives a lot of tags and which tag is associated with which driver or device?

Also have to ensure that running poolmon on the Prd system will not cause any issues to the system performance.

Thanks for all your help.

interpretation of poolmon output is task of the organisation telling you to run poolmon.

poolmon will not effect the overall performance of a system.

Hello,

here are some opinions from other users facing this problem -> <a href="http://www.eventid.net/display.asp?eventid=2019&eventno=661&source=Srv&phase=1">link</a>

Some common points are:

- an anti virus program can cause it

- old drivers for the network card (especially 3Com)

Hope it helps.

Hi Norman,

Thanks for the response. Some additional information I would like to provide.

This is the extract from the event log.

However I would try out other options mentioned by you and get back.
