Source: GroupWise Message Transfer Agent.
Explanation: The MTA could not start another thread for an inbound connection.
Possible Cause: The maximum number of inbound connections as specified by the /tcpinbound startup switch has been reached. The default is 40 inbound connections.
Action: Increase the setting of the /tcpinbound switch to allow for more inbound connections. There is no maximum number of inbound connections. They are limited only by available system resources. See "Adjusting the Number of MTA TCP/IP Connections" in "Message Transfer Agent" in the GroupWise 6.5 Administration Guide.
