Memory Leak error, that only occurs, when i rename my server, and give a specific ip address?

I've got a memory leak error on my windows 2003 std edt server. the strange thing is, it ONLY happens if i rename the server, and change its ip address to that of an old server on our domain. I'm trying to upgrade our fileserver, so i've got a brand new dl380, with windows 2003 std edt. It's been running for a month now(on the domain) all ok, no errors at all. On the weekend, i planned to put it live. I took the old fileserver (called fileserver, Win2k) off the domain, and into a workgroup, changed its ip address and re-booted, all ok. I then started work on the new fileserver (called temp2), i dropped it into a workgroup, changed its name to "fileserver" (left in workgroup) and re-booted. I then changed it IP address to reflect the original fileserver's address, re-booted. I then joined the new fileserver, to the domain. Everything looked good all the mapped drives worked fine. BUT, about an hour later, i could't access the new fileserver, tried pinging, but that failed as well. Went to site, checked out the event logs, and there were lots of error messages stating: "the server was unable to allocate from the system nonpaged pool because the pool was empty". I restarted the server this fixed it, but it then died about 2 hours later. I reversed the process of naming it, as stated above, and now its back to Temp2, and there are no problems? How can the change of name and ip address cause these problems?

I've found an article on the hp website which has all the error messages and symptoms that i'm having, but, this error is constant, and was resolved by updating Landesk software, i've attached the errors:


we have a compaq dl380 g2 server with windows 2003 reporting memory leaks once a week, becomes unresponsive and has to be hard reset.
all hardware drivers/bios/firmware has been updated without solving the problem.

the server has the following software installed:
W2K3 Server Std. (member of an AD)
HP Utilities
IBM Tivoli Storage Manager Client
LanDesk 8.5
MSDE
Symantec Antivirus Client

the server runs for about a week without problems and then becomes unresponsive (no logon possible due to lack of ressources) with the following event entries:

Try removing ALL HP management agents and tools from your box before renaming it. You can reinstall them afterwards. Also check if there are newer versions to download from HP.

If it doesn't help, also remove before renaming

> IBM Tivoli Storage Manager Client
> LanDesk 8.5
> Symantec Antivirus Client

Hope it helps,

Michael

Thanks for your advice, but can i ask, why don't these applications, cause a memory leak, before i rename it? As i said, this problem only occurs, after i've renamed the server, and changed the IP address?

Thanks

I remember having a lot of troubles with HP agents under different circumstances.
They bring their own web server and stuff I don' t like but you have to install them otherwise you can't manage your servers.
I'd guess they store the server name and/or IP address during setup and if you change it later some subroutines wreak havoc because the name has changed.

You can go and try to find the culprit by using perfmon to watch each process for allocating nonpaged memory and not freeing it.
Start perfmon and select:
Process -> Pool Nonpaged Bytes -> All instances

Ctrl-H turns on highlighting, just browse through the indicator list until you find the one going up. Since you're talking about hours it should go up quite fast.

Hope it helps,

Michael

Hello,

I removed all agents, but still problematic. Managed to get the poolmon logs this morning, when it was in a "locked" state, and found this:

I assume thats a mcafee tag (we have mcafee av). I will remove mcafee tonight, once i confirm the tag. I'll keep you posted.

Never saw this with McAfee but everything is possible... I just wonder because you mentioned Symantec Antivirus Client in your original post. I hope you don't have 2 anti-virus programs installed on the same system?!?

And I must admit: I'm not impartial when it comes to HP agents ...;-)

Hello,

Resolved the problem. It was related to mcafee. And they have a patch to resolve this on there website (you'll need at least patch 11)

Applied the patch, and monitored using poolmon, all ok.

Thanks for your help
