XCON: MTA Is Leaking During Content Conversion

ID: Q232604

The information in this article applies to:

Microsoft Exchange Server, version 5.5

SYMPTOMS

After you configure an X.400 connector as shown below to disallow MS Exchange Contents to an Exchange Server site, and you send several messages out this X.400 connector, you may see a small but noticeable memory leak. This memory leak is logged just before content conversion is done.

X.400 Connector Configuration

On the Advanced tab, click X.400 Link Options, and clear the Allow MS Exchange Contents check box.

CAUSE

In this configuration, the received native MDBEF formatted message must be converted to pure X.400 (P22) format. During this conversion, a memory leak occurs.

RESOLUTION

To resolve this problem, obtain the latest service pack for Exchange Server version 5.5. For additional information, please see the following article in the Microsoft Knowledge Base:
