I had a similar problem with the portland Fortran compiler. I new that this was not caused by a network problem ( I run the code on a single node with 4 CPUs). After I tested pretty much anything, I decided to change the compiler. I used the Intel Fortran compiler and everything is running fine. It could be a PGI compiler voodoo :)
