Hi Gscheffen,
Based on what your are describing I would say that either you have a memory
leak or you are having performance issues with your Disk drives.
Also I noticed in your post that you are running a nightly defrag of your
Exchange server. Microsoft does not recommend ever running defragmentation
utilities on drives that contain Exchange databases. These can do harm to
the databases and they will not gain you any performance as the databases
will still be random reads and writes based on usage and the internal
structure of the database.
You are going down the right path by using the Exchange performance white
paper. What I can recommend is that you try the following actions.
1) Apply the latest rollup fix from Microsoft:
http://www.microsoft.com/downloads/details.aspx?familyid=363A57A4-8BED-4BBB-BBE4-ABC11AB04611&displaylang=en
2) Download ExBpa from www.exbpa.com and run the tool against your
Environment. This tool should help to reveal if you are not ideally
configured for Exchange performance.
3) In your perfmon counter logs concentrate on the sec/read and sec/write
counter under physical or logical disk. The average values should not
exceed 0.020 seconds for optimal performance. Also you should not see any
spikes greater than 0.100 seconds.
4) Remove 3rd party software from the server one at a time. This will help
to eliminate what if any 3rd party software is causing this issue.
Hope this helps,
