I wonder if you could try it with the Uniprocessor kernel and see if
your problem goes away.

FYI, the machines we're having the problem with are RHEL4 with a kernel of:

Linux 2.6.9-55.ELsmp #1 SMP Fri Apr 20 16:36:54 EDT 2007 x86_64 x86_64
x86_64 GNU/Linux

Note that 2.6.9-55 in RHEL speak is probably closer to 2.6.21 than
2.6.9, since they back port tons of stuff, but keep the same version number.
