Fault-tolerant agents unlink from mailman on a domain manager

A message is received in the maestro log on the domain manager from mailman for each of the fault-tolerant agents to which it is connected. The messages are as follows: 
MAILMAN:06:15/ + ++++++++++++++++++++++++++++++++++++++++++++++++ 
 MAILMAN:06:15/ + WARNING: No incoming from <<workstation>> 
                 - disconnecting. [2073.25] 
MAILMAN:06:15/ + ++++++++++++++++++++++++++++++++++++++++++++++++
These messages usually occur in the 30 - 60 minutes immediately following JnextPlan.

Cause and solution:

This problem is normally caused by a false timeout in one of the mailman processes on the domain manager. During the initialization period immediately following JnextPlan, the "*.msg" files on the domain manager might become filled with a backlog of messages coming from fault-tolerant agents. While mailman is processing the messages for one fault-tolerant agent, messages from other fault-tolerant agents are kept waiting until the configured time interval for communications from a fault-tolerant agent is exceeded, at which point mailman unlinks them.

To correct the problem, increase the value of the mm response and mm unlink variables in the configuration file ~maestro/localopts. These values must be increased together in small increments (60-300 seconds) until the timeouts no longer occur.
