It is hard to tell - you don't give much information!  However, using LAM5.2
I experienced a problem that might be related to yours: when MPI_IProbe
was extensivelly called, in some situation (???) it blocked.  I haven't 
solved the problem, but in my case I could use the blocking version.

Is there a list of known bugs for LAM5.2?
