We consistently have memory issues with our large SharePoint implementation. These are great tips that I can now pass onto the developers and help bolster our SharePont Dev standards.

Hi Stefan,

This post displayes the information on what can cause a memory leak in the w3wp.exe process, is there anything that can cause a memory leak (under the context of MOSS server) in the SQL Server process: sqlservr.exe?

I am performing a lot of imports, one after another, and I suspect that such thing may be the cause.

Hi Mor,

import operations can lead to high memory usage on SQL server as well. That's why we recommend 64-bit architecture on SQL server.

But it should not lead to a leak.

If there would be a leak it would be a bug in SQL server.

Cheers,

Stefan

Stefan,

Would it be possible to get your sharepoint w3wp to use more memory if you had a windows 2003 enterprise server (8 gig ram) with PAE enabled?

re: Dealing with Memory Pressure problems in MOSS/WSS

Stefan_Gossner — Fri, 21 Nov 2008 01:58:54 GMT

Hi Matt,

no this will not help. PAE allows a computer to address more physical memory. Not more virtual memory.

The virtual memory of a process is always 4GB. 2 GB system and 2 GB user mode RAM.

So PAE would allow you to run more processes without a need of paging. But not to address more memory within a single process.

Cheers,

Stefan

Stefan_Gossner — Fri, 21 Nov 2008 01:59:46 GMT

Hi Matt,

just to add: the solutkion for your problem is 64 bit technology.

Then the virtual memory in a process becomes bigger.

Cheers,

Stefan

Thanks Stefan!

I had a feeling that was going to be the answer. Unless we can get our WFEs replaced with 64 bit servers, all we can do is add some more regular 32 bit WFEs to the farm. Well that and write better code.
