There really isn't enough information in your e-mail for us to provide
any real advice. You might want to run your application in a debugger
to see where the failure is occuring. The "Debugging MPI programs
under LAM/MPI" section of the LAM FAQ provides some advice on debugging
MPI applications.
One note - that error message doesn't look like a LAM error message.
Are you sure you are using the LAM/MPI libraries and binaries?
Hope this helps,
Brian
