The Microsoft Exchange Information Store Service may intermittently stop responding during database transactions and an event ID 623 message may be logged in Exchange 2000 Server (892396)

SYMPTOMS

On a computer that is running Microsoft Exchange 2000 Server, the Microsoft Exchange Information Store service may intermittently stop responding (hang) when it tries to update the mailbox table during a database transaction.

Additionally, the following event may be logged in the Application event log:
Event Type: Error
Event Source: ESE
Event ID: 623
Computer: computername
Description: Information Store (2048) The version store for instance 0 ("c49a179d-ac1f-4894-8211-0c2917d34500") has reached its maximum size of 108Mb. It is likely that a long-running transaction is preventing cleanup of the version store and causing it to build up in size. Updates will be rejected until the long-running transaction has been completely committed or rolled back. Possible long-running transaction: SessionId: 0x1B6525A0 Session-context: 0x00000000 Session-context ThreadId: 0x00000AF8
