Yes. I did check the code with Intel Thread Check (and earlier through VTune) and that's how pin pointed the problem. I would have imagined this (acquisitin of the lock that is) to be possible for WRITE but not for _for_cpstr.

If anyone aware of a list of FORTRAN functions (like WRITE) which would result in acquisition of a lock?

Thanks,
