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.
