I have a client running Exchange 2000 (part of SBS 2000), with the latest

service pack installed (3).



Occasionally (say, weekly), the Information Store service goes a little

crazy, with it constantly chewing 40 - 50% CPU time.  Users are unable to

use the system as the clients constantly show 'downloading'.

The service does not stop successfully: You have to kill it or reboot to

clear the problem.



I've checked the usual: Event Logs , etc, and there is nothing recorded for

this.



Does anyone have any idea what is causing this?

Hard to tell based on just this piece of info.



Try to disable your Antivirus software to start with, especially your

File-based AV.

I have basically the same problem (not using SBS in this case) and just

posted a thread on the General newsgroups.

We also have this issue & have narrowed it down to our Sophos antivirus "Puremessage" software. We are currently awaiting an return call from Sophos engineer to discuss this issue.

Hi Andy,



I am enountered a similar problem. I am running Exchange 2003 on xeon Piii 700 (single processor) hosting only 20 users at the moment. I have problem matches your post, the Store.exe seems to use very high memory and processor. As I checked the Task manager, the memory usage is increasing and never goes back down, eventually the service freezes, but the server still running at a reasnable speed. can anyone confirm that is this because exchange 2003 cannot run on Xeon Piii 700 (single processor with 1500 RAM)? or is it something is still not configured properly.



Thanks



Regards

Minh
