MPI-HMMER segmentation fault mpi error

Dear all

I have compiled mpi-hmmer recently openmpi (if not mistaken) ... when
i run it using a small dataset it works fine ... but when i input a
big dataset to search against .. like about 200MB ... it crashes on
the first node, exits with "segmentation fault" and mpi-related error
"errno=111" which is a "connection refused" type of error ... any clue
on this? i dont think its mpi related, nor it is an ssh issue ... or
is it? since i'v tried running the same problem on a compute node and
it worked fine with no errors or such.


What im sure of is that mpi is working fine as other software using it
are working as expected ...

any experience with such error?


Thank you guys if you ever read this ... :) and hopefully guide me to
the solution
