SYMPTOMS
If too many link state changes occur because of changes in network topology, the message transfer agent (MTA) process may generate non-delivery reports (NDRs) for some of the messages. The following warning messages may be logged:

Time: 3:08:37 PM

User: N/A

Computer:

Description:

The MTA is unable to route a report for message C=US;A= ;P= ;L= -020208210308Z-521102 to  DN:CN= ,CN= ,OU= ,O=  -- C=US;A= ;P= ;O= ;S= ;G= ;. MTA object at fault: 060009B3. Check the routing table for a possible incorrect routing configuration. (MTA DISP:ROUTER 16 40) (12)

This problem typically occurs on the bridgehead servers. Also, if you monitor the Private Bytes counter of the MTA process, the counter shows a memory leak, and memory use by the MTA process is very high (sometimes up to 2 gigabytes [GB]).
