TITLE   :XFOR: Event 56106 Occurs When Using SNADS or PROFS Connectors
PRODUCT :Microsoft Exchange
PROD/VER::5.5,5.5 SP3
OPER/SYS:
KEYWORDS:exc55sp3

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

 - Microsoft Exchange Server, versions 5.5, 5.5 SP3 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you use the Microsoft Exchange Connector for SNADS or the Microsoft
Exchange Connector for IBM OfficeVision/VM (PROFS), mail may stop flowing
between host-based systems and Exchange 5.5. The following entries may be
reported in the Microsoft Exchange Connectivity Administrator:

   qm(1700) LME-PROFS-DIAMEX(01d8) 1 56106:{Invalid state}: Could not read next
   queue item from vm2mex.in

   dia2mex(1584) LME-PROFS-VMDIA(0222) 4 04103:Queue vm2mex.in depth threshold
   has reached the maximum number specified. Current 10, Maximum 10

CAUSE
=====

This issue can occur if one or more of the index files which holds pointers to
the message objects has been corrupted. This condition may be caused by file
locks from file-based antivirus software or a bad disk write operation to the
index file.

RESOLUTION
==========

To resolve this issue:

1. Stop the affected Exchange connector from the Services Control Panel. For the
   SNADS, stop the Exchange SNADS Connector service. For OV/VM, stop the
   Exchange PROFS Connector service.

2. Delete all index files with .qcr extensions in the following directories
   related to where message flow has stopped:

    - If mail flow from SNADS to Exchange has stopped, delete
      \Exchsrve\Connect\Xchconn\Q\Dia2mex.in\<xxx>.qcr

    - If mail flow from Exchange to SNADS has stopped, delete
      \Exchsrve\Connect\Xchconn\Q\Snads.in\<xxx>.qcr

    - If mail flow from OV/VM to Exchange has stopped, then delete
      \Exchsrve\Connect\Xchconn\Q\Vm2mex.in\<xxx>.qcr

    - If mail flow from Exchange to OV/VM has stopped, delete
      \Exchsrve\Connect\Xchconn\Q\Via2vm.in\<xxx>.qcr

3. Restart the Exchange connector.

MORE INFORMATION
================

The indexes are rebuilt when the Exchange connectors are restarted.
