I guess you mean "stuck". When a parallel run goes bananas, it can
be hard to understand why. Print output to the terminal, not to file.
Add print statements (using "write (*, ...", that should actually 
print something from each process), stop commands (use
"call stop_run(.false.)") and try to locate what happens and where.
