[torqueusers] PBS log file copies

Hello,

I have installed and configured TORQUE on a small (2 socket, 8
cores/socket) Debian linux server, with NUMA and CPUSETS enabled.
Everything is working very well, with one exception:  The PBS logfiles
from the '-o' command line option are not being copied to the desired
destination.  The copies fail, so the files stay in the 'undelivered'
directory.  Here is an output fragment from 'daemon.log':

-------------------------------- snip --------------------------------

 
I interpret the error as 'scp' trying to copy from one physical node to
another at ( rosmond at fir ).  But since these are NUMA nodes, this can't
work, but a simple 'cp' to the destination location and file name would.
Is this correct?  If so, what do I need to do to configure the system to
get successful copies?

BTW, we have 2 other nearly identical NUMA systems that don't have this
problem.  I have tried to mimic their configuration as closely as
possible, but something must be different, but I can't find it.
