This case has almost always worked correctly for us. We haven't seen any 
bug reports for this. We need more information to figure out what's 
going on.

1. Did you set a separate host file environment? Are you using any 
resource manager (like SLURM, PBS, ...) in your environment? The reason 
I'm asking is "mpiexec -n 8 progfile" itself will not know anything 
about hostB, unless you have it this information through some other means.

2. Are you seeing any errors while running the job before you try to 
kill it?

3. Did you try running one of the MPICH2 example programs (./examples/cpi)?
