What's up with Domino Memory usage and Stability on Windows 2008 Server?

Hello there

i’ve some trouble with Domino 8.5.X and Windows W2k8 Server (Standard and R2 i tried em both)

For Example:

i’ve installed a Notes Server on Windows 2008 Standard 32bit, i installed traveler+smtp task on it.

At this moment the Server needs around 1,5GB Memory, doing just nothing. (no active users)

with 100 Traveler Users the Server needs all 3,25GB memory and crashes sometimes.

When i install the same Setup on Windows 2003, the Server needs around 480MB (no active users)

Before, i had sametime traveler smtp on this W2k3 machine running and never had trouble with memory usage or anything, dont got exact numbers here.

another example:

Running domino 8.5.1 with sametime 8.5 on Windows 2008 Standard, the Server crashes when i shutdown Domino with “quit”, because of sametime task not shutting down.

This with no active users / load on it.

Same Setup on Windows 2003, Server runs and shutdowns fine. (and way faster).

At the moment i’ll never install a Domino Server on W2k8 again.

I’ve to say that we’re running on ESX 4.0, maybe thats a point too.

Anyone else made same expiriences with Windows Releases? got any tips?

Thanks!

kind regards

Tibor

Subject: Similar

I am having a similar issue. Although, keep in mind there is the Virtual Memory and Memory. Usually the one that matters its the virtual one.

But Domino seems to be a memory hog in Wk8.

Subject: Hack is to buy more memory … it’s cheap …

  • If the “solution” is more memory then why it happens may be less relevant than fixing it. 3.5GBytes seems a bit light for any modern server, anyway. Bump it to 8 at least.

  • My experience is that real physical memory is the only important value. Virtual memory is useless because it’s thousands of times slower than physical memory. Ideally your server will use as little virtual memory as possible, for best performance. Bear in mind I’m not an admin, this is simply my observation running servers and clients and VMs all simultaneously. Soon as the machine runs out of real memory and hits virtual I can tell … its slows to a snail’s pace. A real server with high-performance multi-channel disk array may not be so dramatic a change, but the fact remains that disk is slower than RAM.

Hope this helps…
