Store.exe limited but still growing - Microsoft Exchange

Simon -

You have not mentioned why you lowered the cache to such an extraordinary
low value. You did mention any virtual memory error events, like the
9582's. Please keep in mind that just because the Store.exe appears to be
using a lot of physical and virtual memory (working set and virtual bytes),
does not mean you should lower the cache to something like 262MB. By doing
so, you are putting a lot more pressure on the disk subsystem, which in many
cases will lead to other kinds of undesired things... for instance, disk
bottlenecks (latecny, etc.). The lowest value I would recommend lowering
the cache to would be "147456" (= 576Mb). This is the Exchange Product
Group's recommended minimum. It's good to use on Windows 2000 Standard
Servers that can not use the /3GB switch and severe VM-constrained servers.
Which leads me back to my original thought... you did not mention the 9582
Events in the Application Event Viewer Log.

I would suggest you do not adjust this cache unless you need to. I would
recommend you remove the value in AD, so the value reads "Not Set", allowing
the Store to use the default size of 858Mb. That default cache is mapped in
the virtaul address space, where each process gets 2GB of virtual addresses
to use (regardless of how much RAM is installed). That VA space can be
increased from 2GB to 3GB by placing the "/3GB" switch in the boot.ini
provided: 1] the server has 1GB RAM or more; and 2] the OS is at least W2K
Advanced or any version of W2K3.

In summary, if the Store is generating 9582 events then the cache can be
adjusted to combat the problem.

Hope this helps.

Thanks Michael for the information, but how can I
restrict the memory use of exchange? We have just 10
users and there are some other programs running.
