SYMPTOMS

The Microsoft Exchange Message Transfer Agent (MTA) stops with the following error in the Windows NT Event Log:

Event id: 2143

A fatal MTA database server error was encountered. Call Microsoft Product Support. Unrecoverable error: ODXEOLST - Value Number too large. About to terminate. Called from MTA. Procedure 233. Object ID: 06000045. Attribute ID: 2. Attribute value number: 1. Referenced object: 06000041 (00000000 => N/ ). Referenced object error ODXBMFUL - Bitmap full. [1 DB Server DISP:RESULT 18 101] (16)

CAUSE

The MTA terminates with Event Id 2143 during rerouting. An attempt is made to read a message beyond its boundary condition. This depends on whether the MTA was reading from cached data or not.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 4.0. This problem was corrected in the latest Microsoft Exchange Service Pack. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base:
