Source: GroupWise Post Office Agent; message transfer protocol.
Explanation: The POA is configured to communicate with the MTA by way of TCP/IP. The MTA has stopped responding in the middle of a communication.
Possible Cause: The MTA is running on an overburdened server, so it cannot respond to the POA in a timely manner.
Action: Add resources to the MTA server so that the MTA can function properly.
Action: Move the MTA to a different server where more resources are available. See "Moving the MTA to a Different Server" in "Message Transfer Agent" in the GroupWise 6.5 Administration Guide.
Possible Cause: The server where the MTA is running has gone down.
Action: Check the status of the MTA server. Reboot if necessary.
