Sandhya,

Can I have the full logs from one of the JMeter servers and the
controller (maybe through pastebin.com) after you've made the changes
described below.  I'm struggling to think as to why it would matter what
test plan you're running. Maybe someone else on the list will have
insight into why you can run one jmx and not another. I wouldn't think
it matters. Are you perhaps running in a way that seems out of the
ordinary?  Not the test script, but the way in which you've started up
the servers?

I've been all over the source code, and even tried this myself and for
me, the 'main' thread is the only thread to interact with this. 

Can you try setting these property in jmeter.properties:
log_format_type=thread_prefix  #uncomment this line
log_level.jmeter.engine=DEBUG  #uncomment these and set to DEBUG 
log_level.jmeter.threads=DEBUG  #although we'll only see INFO anyhow.

I'm interested to see if these 3 lines differ. You can see from mine,
the 'main' thread did all 3 of them. It seems in your case that the 1st
and 2nd are happening from two seperate threads.

When I say 'you did not create' I mean this; are you restarting the controller while the load generators are either still executing a test or not exiting properly?  I mean, the controller is a brand new instance while the load generators are still the same instance from before.
