Exchange 2003 Mail Store Unmounts every few days

Exchange 2003 (R2) Mail Store unmounts after a few days.  Sometimes a "low on virtual memory" taskbar bubble is there when I unlock the screen after the mail system has gone down.  However after looking at the task manager, virtual memory is ok.

I have tried checking the event viewer (application) but it has been spammed with Event ID 3005's multiple times a second. (Unexpected Exchange mailbox Server error).  This seems to truncate out anything that might be helpful in troubleshooting.  Any may be the cause of the virtual memory error?
System Event Viewer shows a low virtual memory pop up (ID 26) at the time the server stopped responding.
I increased the virtual memory a week ago but it has not solved the issue.

A reboot sets things right again for a day or two.

A few things I have checked.
Max Database size is set to 500gb currently 56gb.
IIS setting for Exchange-oma have been check and seem correct.
Plenty of HD space.

Thanks for any help.

If it is a performance issue, then Start with EXBPA scan and fix all the errors/warrnings.
Then if there is no improvement.. go on to collect performance data of the servre and proceed further

The 3005 event are Activesync event's and can usually be ignored.

Do you have iPhones running iOS 4.0 on your network by any chance?

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

Basically - your iPhone 4.0 devices are killing your server due to a problem with the iOS 4.0 release.

Ok, I have checked to make sure all iPhones are 4.0.1 or higher (none were on 4.0)
Also, the EXPBA came back with only 1 suggestion. Lowering my paging file size.....
Was at 4gb moved to 6gb after getting the full virtual memory errors.  I have 4gb of Ram.

Can you please check your Activseync configuration against my Article and make sure that is 100% happy.

You presumably have Exchange 2003 Enterprise?

Exchange 2003 Standard x32
500 users

Okay - so with standard the max database size is 75Gb and that's it.  You mention the size is set to 500gb - that's not going to work on Exchange 2003 Standard.

Please set the max database size to 75Gb and then check the key is set correctly.

Are there any 1216 Event ID's in the Application Event Log?

SedrynAuthor Commented:
Ah, that has to be the problem.  If I add up my EDB and STM files I get a total of 85GB
I guess I need to have my users do some archiving until I can move to Exchange 2010 next year.
Dang.

Alan HardistyCo-OwnerCommented:
The size of the database is the size of the .EDB plus the .STM file minus the free space noted in Event ID 1221.

Too large a database is the most logical explanation for the problem you are facing.

Archiving is about the only solution short of upgrading to Exchange 2007 / 2010.
