XCON: Recovery Checkpoint Size Different, MTA Connection Fails
ID: Q187929
|
The information in this article applies to:
-
Microsoft Exchange Server, versions 5.0, 5.5
SYMPTOMS
When the message transfer agent (MTA) on one Microsoft Exchange Server
computer attempts to connect to the MTA on another Exchange Server
computer, it proposes a particular checkpoint size. When the second MTA
accepts the connection, it may propose a different checkpoint size. If the
connection ends unexpectedly, the first MTA attempts to connect again.
However, the second MTA may not propose the same checkpoint size that it
originally proposed, even if the first MTA does.
Note that if the first MTA established a monologue connection, the
inconsistency between the original session protocol data unit (SPDU) and
the recovery SPDU may prevent the first MTA from reconnecting after the
original connection ends.
