Symptoms: 

Infrastructure Manager frequently disconnects to the primary hub, but probes in the primary hub are functioning and all permanent queues are ok.

In the hub.log the following errors are recorded:

Jan 21 07:32:00:079 [22920] hub: General error on session

Jan 21 07:32:00:079 [22920] hub: Disconnecting queue route for 'baseline_engine.HTCAAPP01.BASELINE_CONFIG' (error 3 on queue)

In the Nimsoft Service Controller window on primary hub server, there is no robot information and client connection to primary hub drops.
