Ok, switched track interface to eth0, but still get the same loop...

I dont believe we are using HT P4s. From /proc/cpuinfo: Intel(R) Pentium(R)
4 CPU 1.80GHz. Both directors have the same setup. I think the smp was
chosen because right now we are running these as test boxes. If all goes
well though, we will get dedicated server boxes for production use (most
likely HT P4s). Since this is not a HT proc, should this still cause
conflict?
