I believe this error message says it all -- one of your processes has
died.
Specifically: MPI_BARRIER isn't what caused your app to die;
MPI_BARRIER is the function that noticed that the other process was
dead, reported the problem, and then aborted all remaining MPI
processes.
Your program is a bit too long for me to debug; Brian's advice of
running through debuggers is probably your best bet. Also check for
corefiles that may indicate where your program died.
