I think its something else. I think this has something to do with POSIX,
is that a wrong assumption.

Rajeev,
	The only thing I can think of is that you're using "blade1" --
which is 
set in the host_name variable for that host in your .cfg's.  I'm not 
convinced that when you run a plugin from the command line, it knows to 
look up what the actual IP/hostname is of blade1 in the cfg's.  I would 
try running the plugin from the command line with the actual IP/hostname

and see what happens.
