Note that in the example above, these events appear in the order in which they occurred; they appear in this order if the Event Viewer is configured to view the oldest events first.

CAUSE

The MTA terminated due to a resource shortage. The MTA is attempting to add local resources for remotely-hosted connectors such as the Internet Mail Connector (IMC) or the MS Mail Connector (MSMI).

WORKAROUND

Change the following registry entry to 0x20 to avoid this resource shortage:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
                     \MSExchangeMTA\Parameters\MT gateway clients

The default setting is 0x08 and is adequate under normal conditions. However, when an installation has several gateways and connectors configured, additional resources may be required.
