Q242944: XCON: MTA Generates a Large Number of Event ID 2125s

Article: Q242944
Product(s): Microsoft Exchange
Version(s): winnt:5.5
Operating System(s): 
Keyword(s): exc55
Last Modified: 06-AUG-2002

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Exchange Server, version 5.5 
-------------------------------------------------------------------------------

SYMPTOMS
========

The message transfer agent (MTA) may generate a large number of event ID 2125s
that are similar to the following, even though mail flow is not affected:

  Source: MSExchange MTA
  Type: Warning
  Category: Resource
  Event ID: 2125

  Description: Statistics for DBI call (DB Server) : file writes DISP:FANOUT,
  reads 11, cache hits 124, misses %5. Attribute %6, value number %7, Object
  ID: %8 (00000000 => N/A). Caller %12 [%9 %10 %11] (8)

CAUSE
=====

This issue can occur if the MTA does not write to the .cfg files correctly when
the MTA processes new messages. This issue occurs most often when one of the
Info*.cfg files is an incorrect version or is corrupted.

RESOLUTION
==========

To resolve this issue, use one of the following procedures, as applicable:

- If the object ID is referenced in the event ID description as shown in the
  following example

  Event ID: 2125
  Type: Information
  Category: Field Engineering
  Description: Statistics for DBI call (19): file writes 0, read 0, cache hits
  1, misses 1. Attribute 84, value number 3, Object ID: 0600003A (00000000
  => N/A). Caller 117 (DB Server DISP:ROUTER 11)(8)

  perform the following steps:

  1. Note the object ID that is included in event 2125 (0600003A in this
     example).

  2. Remove the .dat file that has a file name that is composed of the last six
     digits of the object ID from the Mtadata folder (the Db00003a.dat file in
     this example).

  3. Run the following command:

  <exchsrvr>\BIN\mtacheck

  4. Restart the MTA.

  5. Reapply the relevant Exchange Server service packs and any post-service
     pack fixes.

- If no object ID is included in the event ID description, apply the latest
  Exchange Server service pack, so that all of the files are the correct
  version.
