XCON: MTA Can Stop After Generating an Event ID 9405 (197281)
The information in this article applies to:
- Microsoft Exchange Server 5.5 SP1
This article was previously published under Q197281 SYMPTOMS
The Exchange Server message transfer agent (MTA) may generate an
event with the following text:
Source: MSExchangeMTA
Event ID: 9405
Description: An unexpected error has occurred which may cause the MTA
to terminate. Error: ExchHeapFree failure 87. [BASE DISP:FANOUT 12]
(16)
These events are sometimes associated with the MTA when it appears to
stop processing messages, and you must stop the service from Task
Manager and restart it to resume message flow. The Calls.out file may
indicate that the Process Heap status entry, Heap 0x01070000, owned by MTA
routine 142, is invalid.
CAUSE
The MTA can encounter problems if it is configured to generate
content encoding for a size of 2 KB, which is turned on when the heuristics
bit is set. This setting is used to accommodate other X.400 MTAs that are
unable to handle content encoded to larger sizes. The heuristics bit for
2 KkB-encoding is 256.
RESOLUTION
To resolve this problem, obtain the latest service pack for Exchange Server
version 5.5. For more information, please see the following article in the
