On a Microsoft Exchange Server 2007 mailbox server, the Microsoft Exchange Information Store service (Store.exe) crashes intermittently. Additionally, the following errors are logged in the Application log:
Time: Time ID: 4999 Level: Error Source: MSExchange Common Machine: Computer Message: Watson report about to be sent to dw20.exe for process id: Process ID, with parameters: E12N, Build Type, Version Number, store.exe, mdbrest.dll, XXXX, c0000005, XXXX, Version Number. ErrorReportingEnabled: False
Time: Time ID: 7034 Level: Error Source: Service Control Manager Machine: Computer Message: The Microsoft Exchange Information Store service terminated unexpectedly. It has done this XX time(s).
Note When this issue occurs, users cannot access their mailboxes.
This issue occurs because a string exceeds the buffer size when the Exchange server reads a row from the Exchange mailbox store database. Therefore, the Store.exe process crashes.
Note This issue only occurs when ExTRA tracing is running and the tagFindRow trace tag is enabled during a troubleshooting process.
To resolve this issue, install the following update rollup:
