[Samba] Is samba or a kernel bug causing my FC4 server to crash?

I've got a fully updated Fedora Core 4 server crashing hard every week or
two. I use Samba via smbmount and autofs to read & delete log files on 17 XP
boxs and 6 NT4SP6 boxes as well as a couple other Windows files servers
every 5 minutes. The first indication of a problem I get is smbmount stops
working, then the server becomes unresponsive to the point where only a
power slam will fix it, and it does fix it...for a few days.
I've got Samba 3.0.14a-2 installed and have been updating my kernel as often as
a new one is released. Currently I'm running 2.6.14-1.1637_FC4smp.
Here are 4 seperate crash excerpts of the sytem log. Anybody know how to tell
if samba is involved and if so, if it is responsible?
