Mark,
Thanks for reply. I did check it again with the pmDebug flag. The
OUTPUT on two machines are DIFFERENT. On the faulty machine, even
after I say pmUseContext(remote context), the pcp function calls are using
the local context.
I am attaching the code with this mail. Also, I have attached the outputs
written on to a file.
'output1' is the output on faulty machine and 'output2' that of correct
one. (The output clearly differ on line 8).
I would really appreciate if you can let me know why its happening.
Thanks,
Sadanand
