XFOR: Message Delivery Is Slowed or Stopped to SNADS

ID: Q193346

The information in this article applies to:

Microsoft Exchange Server, version 5.5

SYMPTOMS

The LSDIAMEX process of the Exchange SNADs Connector may shut down and stop delivering messages to Exchange. You may see an error message similar to the following in the Exchange Connectivity Manager's log browser:

Queue threshold exceeded. Suspending SNA Link. Please Reduce Disk
Usage.

CAUSE

When a message with an embedded mail object is sent from the host to Exchange using inbody addressing, the message arrives in the SNADS connector's Gateway Mail List input queue as two separate mail objects. The SNADS connector processes the message body (the first mail object in the queue) correctly but shuts down when processing the embedded attachment. The code tries to close the file handle of the embedded mail object, which had been previously closed when it was being added into Exchange as an attachment. Note that the error only occurs when the embedded mail object is added to Exchange as an attachment.

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 Microsoft Knowledge Base:
