Resolution:
When multiple adapters are running in the Distributed Queue(Load Balancing)

mode, the scheduler will assign the task to a particular adapter depending on its

Listener Task. The higher the listener task, higher is the load adapter takes. It is

not related to the Thread Count and number of CPUs.

Please refer to the chapter 'Distributed Queue' in the TIBCO Rendezvous  concepts documentation
for more information on Listener Task(Worker weight).
