XCON: Exchange Server 5.5 Post-SP3 Message Transfer Agent May Stop Responding After Reporting Event ID 4283 (266792)
The information in this article applies to:
- Microsoft Exchange Server 5.5 SP3
This article was previously published under Q266792 SYMPTOMS
In a site in which servers have many X.400 connections, some over slow lines, a message transfer agent (MTA) may log an event ID 4283 message that contains a description that is similar to the following:
Unable to recognize an internal message identifier. Internal connection handle (LPI) 1-15-4 Error code: 8465 [POP4 POP4 UP 6 228] (14)
The error code that the description quotes may also be 8464.
Then the MTA stops responding, and you must either stop the MTA manually or restart the server. This occurs in build 5.5.2651.61 or later of the MTA.
CAUSE
This problem can occur if there is an error in the way the MTA processes its internal control blocks.

The fix ensures that after these events are logged, control blocks are managed correctly so that the MTA does not become uncontrollable.
