Kernel Crash with FC3 [glibc?]

My home router machine was upgraded in late December to FC3. The
machine began experiencing times when it would start having a load
average of 1.00 all the time but using top would show no processes
using any CPU. The CPU indicator said that it was at 100% in user
space. No process was listed as being in device wait either.

I took the machine down and did a chkrootkit 0.44 and some other items
to make sure it was not compromised. I then rebooted the box and
watched the wire to see if anything strange was coming up to it.
Nothing. I then went and turned off various processes that were turned
on for small network usage. When I did a 'service nscd off' the box
went into a kernel crash that went on for quite some time (looked like
an infinite loop).

Turning off nscd has dropped the load average to a standard 0.00 again
so I am guessing that there is something it is doing that is causing

I am having problems getting serial console to work so I do not have a
kernel oops at the moment :(.
