SYMPTOMS

The private bytes usage for the message transfer agent (MTA) process can reach up to 2 gigabytes (GB) in an environment where minor revision changes are made to the link state tables. This problem usually occurs on bridgehead servers. Usually, the minor version changes occur when there is any of the following situations (this is not a complete list):
  • A change in the connector settings
  • Misconfigured connectors (for example, an incorrect password)
  • Frequent addition and deletion of connectors
  • Unreliable network
After this condition occurs, the MTA generates the following events for any message that enter the MTA.
