| Description | process name (process id) %3The database engine stopped. |
| Event Information | According to Microsoft : Cause : ESE Event ID 100 indicates that the database engine started. ESE Event ID 101 indicates that the database engine stopped. ESE Event ID 100 is usually followed by a series of other ESE Events describing an online restore, or mounting of information store databases. If an online restore fails to complete, or a database fails to mount, you may receive an Event ID 101, indicating that the database engine has stopped. You may also receive this event when an information store dismounts for any reason. If you try to mount the store again and the store fails to mount, you may receive Event ID 100 indicating the database engine started, and then again receive Event ID 101, indicating the database engine failed to start. In Exchange System Manager, if the arrow points down and is red, which displays on the Exchange System Manager icon, this indicates that the stores are dismounted. In summary, receiving ESE Event ID 100 simply means that the database engine started. It does not mean the information store will mount, since it may be followed by an ESE Event ID 101, which means the database engine stopped. In this case, the store failed to mount. The reasons for ESE Event ID 101 are many and varied. These events by themselves are generic for restoring and for mounting of the information store databases. For examples of causes, there may not be enough permissions on the directory where the database or logs exist to mount the store. There may be missing log files on the production, or in an online restore, there may be old log files that are out of sequence with the log that is mentioned in Restore.env file. There may be file level virus scanning software running against the log file directory. Resolution : In normal operations, if you receive ESE Event ID 100 or ESE Event 101, and Exchange is functioning normally, no user action is required. However, if an online aware restore of Exchange fails or an information store database fails to mount as expected, then ESE Event ID 101 indicates that there may be a problem with the database or its logs. Check the Application log and the System log for related events to determine the exact sequence of events leading up to ESE Event ID 101. |
