I'm not entirely sure what you mean -- how are you blocking in an
MPI_Iprobe? By definition, MPI_Iprobe is non-blocking, and will
return immediately. Do you mean that you are looping over MPI_Iprobe
until flag returns 1?
You might want to run your code through a memory-checking debugger
(see the LAM FAQ for some important notes about this) to see if there
are any non-obvious errors occurring. That is almost always the
first step when tracking down problems like this.
