Hi, my program is giving me this error on one particular machine:
[localhost.localdomain:04889] mca_btl_sm_component_init: mkfifo failed
with errno=17

Errno 17 appears to be File exists. Any ideas why this might be
happening? My program is spawing another module, is there some reason
it would be trying to open this file as well?

I'm running on a 32 bit CentOS 3 machine w/ 1.0.2 installed from source.
  I configured it using both threading options. Below is the output of
ompi_info on the machine that's failing. It runs fine on a different
machine running a 64 bit Fedora Core 4 install.

Thanks,
Jonathan
