MPI/Fortran programming problems

I'm running into a strange error with a Fortran program that I'm running on
It's spitting out:
8 - MPI_BCAST : Message truncated
 Aborting program !
 Aborting program!
p8_3396: p4_error: : 14
rm_l_8_3397: p4_error: interrupt SIGINT: 2
P4 procgroup file is procgroup.
(The first and last lines are my own debugging info)
The line of offending code is this:
This next line works (yes, I know it's a send, but an mpi_bcast of this
array works as well)
This only happens on large bcast sizes. It barfs on a MPI_DOUBLE_PRECISION
of size 25326, but works ok on something on a double precision array of
8442. Very puzzling. I've tried doing mpi_send, but it just hangs instead.
The arrays are declared properly, and the sizes are correct.
