We have been experiencing this problem for the past couple of weeks. Exchange runs until the follow two errors occur and then the Information Store stops. The Internet Mail Service then starts to have problems because the IS is not running. The IMS then shuts down.

We have tried and checked….
- There is plenty of disk space on all hard disk.
- We checked permissions and they look fine.
- We ran the “Error_Checking” utility on the hard disk and no errors were found.
- We tried disabling “Circular Logging”. We still get the errors
- We moved the IS Log files to another disk and we still get the error.
- We ran server diagnostics and found not errors.
