Note: I had a case were I was getting events 623, 1022, 1025 and the following event ID.


Example of a 623 in the application logs:

Event Type: Error
Event Source: ESE
Event Category: Transaction Manager
Event ID: 623
Date: 1/26/2009
Time: 3:34:46 PM
User: N/A
Computer: Computer
Description:
Information Store (4176) Standard Storage Group X: The version store for this instance (2) has reached its maximum size of 155Mb. 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: 0xBD33ACA0
Session-context: 0x00000000
Session-context ThreadId: 0x000015AC
