I've looked at your problem from all possible directions but I cannot find  
any way it could fail! Apparently it is quite simple code. I wasn't able  
to replicate you problem even by forcing two threads to close the same  
file several times each!

Could you please provide more information on the compilers you have used  
on the two different cluster, the exact command line you have used to  
start the job (are you using pools?) and the output of the "env" command  
 from pw.x point of view (i.e. you put env in you job's script).

Finally, please take no offense if this sound like a stupid suggestion;  
the only way I could reproduce you problem was to run multiple copies of a  
serial-compiled executables via mpirun. Could you please double-check it  
is not your case?

cheers
