Memory leak in cpqteam.sys?
We have a IIS that randomly stops serving pages.
1. Found connection_refused errors problems in our intranetservers (Windows Server 2003 SP2) httperr.log file,
2. Googled a little bit and found this http://blogs.msdn.com/david.wang/archive/2005/09/21/HOWTO_Diagnose_IIS6_failing_to_accept_connections_due_to_Connections_Refused.aspx
article
3. C:\> poolmon -b -n
4. Checked the poolsnap.log file and the topmost driver sorted by memoryusage
Tag Type Allocs Frees Diff Bytes Per Alloc
NTID Nonp 12263728 12170319 93409 168397912 1802
5. C:\> cd c:\windows\system32\drivers
6. C:\> findstr /m /l NTID *.sys
cpqteam.sys
Everytime I check the used allocated memory on this server the NTID has grabbed more memroy.
If I let the server run, for 3-4 days the IIS will stop responding and serving pages.
The hardware is ProLiant BL460c G1 with a cpqteam.sys driver version 8.55.0.0.
Any clues?
Kind rega

Re: Memory leak in cpqteam.sys?
1. Upgraded the driver to 8.70.0.0
2. Upgraded HP Network Configuration Utility for Windows Server 2003
I'll see if it helps.

Re: Memory leak in cpqteam.sys?
So far so good...the NTID has not "eaten" as much memory as before...

Re: Memory leak in cpqteam.sys?
I have similar behaviour on a DL360 G5 file server. After 1 - 2 days it stops accepting connections, AD crashes and after a while it completely hangs. Poolmon brought up NTID tag as well. I just have updadet cpqteam.sys to 8.70. At the moment it doesn't seem to consume too much pool memory anymore. Let's wait and hope - crashing fileservers are always a pain ;-)

Re: Memory leak in cpqteam.sys?
NTID still behaves normally, apparently there must have been some fix in v8.70.

Re: Memory leak in cpqteam.sys?
I had the same problem on 2 of 4 Windows Server 2003 Enterprise edition SP2 R2 systems.
Problem started after I installed NCU v8.60 some months ago.
I installed HP NCU v8.70 this morning on all 4 systems.
I'm using 2 NC370T MultiFunction NICs with TOE enabled in a team.
On the 2 systems which were experiencing the memory leak I can no longer launch the HP Network Configuration Utility.
HP NCU 8.70 now reports an error dialog box stating "An error occurred when making a call into the operating system" and after I click OK on the dialog box the NCU disappears from the task bar system tray until I login again.
There are no events in the event log.
Can anyone tell me how to correct this condition?
Regards,
Bob Harrison

Re: Memory leak in cpqteam.sys?
BTW: have you had any problems regarding TOE?

Re: Memory leak in cpqteam.sys?
I upgraded the NIC drivers yesterday for all three of my installed NIC types before upgrading NCU from 8.60 to 8.70.
If you don't upgrade the NIC drivers, the NCU upgrade checks for and complains about NIC drivers which are not up to date with minimum required versions for NCU to operate.
Please note that enabling the disabled NIC and re-disabling the NICs caused NCU managed teams to stop communicating on the LAN and this caused cluster service to hang. I had to reboot both nodes of my cluster a couple of times to get through the enable/disable process. NCU seems to working OK now.
