I initially also thought it might be kernel version related 
(2.6.13.2/PYXIS here), but the problem started
after a "dist-upgrade" where libc was replaced.

I had also thought we had enough variance of 2.4 and 2.6 kernels on the 
list to believe
it wasn't kernel version related.

I tried:

1) kernels 2.6.12 and 2.6.13.X
2) rebuilding glibc with gcc3.3
