Environment

ITMS 8.x

Cause

The task server settings had been reached.  See the settings at the following location in the SMP Console:

1. Settings>Notification Server>Task Settings>Task Agent Settings.   This shows task service configuration information.
2. Settings>Notification Server> Site Server Settings>Task Service>Settings>Task Service Settings.   This shows the task agent settings.  In this case, they had set the site server to "Choose the Task Server to which the agent has the fastest connection".

Resolution

Changed the Task Agent Settings to Choose the Task Server relative to the remaining capacity of each site server.  Then ran the Update Task Service Assignments task.
