cpqcisse.sys Memory Issue

[Craig Ongers]

Hi there, I am having an issue where it seems the HP Smart Array Notification Driver (cpqcisse.sys) is leaking non-paged pool memory. I confirmed it is this driver by using http://support.microsoft.com/kb/177415 as it is definitely this driver ("Ddk" in original Poolmon output) that eats up all of our 128MB of non-paged pool memory after 2-3 days of running. Details of our server can be found below. I already updated the driver and firmware of the RAID adapter, any other suggestions?

HP server (HP ProLiant ML350 G4; BIOS D17) is running a Smart Array 642 Controller (Firmware 2.84; Cpqcissm.sys = 5.80.0.32 Build 1 (x86); Cpqcisse.sys = 6.4.0.32 Build 5 (x86)). OS is Windows Server 2003 with SP2 using /3GB switch and is dedicated to running Exchange 2003 with SP2.

I did not get any replies to my post so I looked further on my own. I found this URL http://blog.dsatkhan.net/2007/09/memory-leak.html which gave me the idea to look at our AV configuration. We were running Trend Officescan 8.0 RTM without the Trend firewall enabled. After installing Officescan 8.0 SP1, post-SP1 patches & rebooting, our system seems just fine again. The HP driver ('Ddk' in Poolmon) is no longer 'leaking' memory.
