[mpich-discuss] mpiexec kills the remote login shell

I am cross-compiling mpich2-1.0.8 with smpd for Khepera III mobile robot.

This mobile robot has a Korebot board which is an ARM-based computer
with a Linux operating system.

The cross-compilation was fine.

Firstly, I logged in to Korebot through ssh.
Secondly, I started smpd.
Thirdly, I ran mpiexec to execute an MPI program (cpi) that comes with
the package.

The result was correct, but when mpiexec was finished, the ssh
connection to the Korebot was closed.
I found that mpiexec kills the sshd process through which I was
remotely connected to Korebot.

I've been looking for the cause, but still have not found any clues.

Could you give me any ideas to solve this problem?

Thank you,
