Given that you can no longer SSH into the server it looks like the
machine is crashing, not Samba.  I've had this problem before with an
early 2.6 kernel (it could've even been 2.6.9) where a bug in my
network card driver (r8169) caused the whole machine to lock up.

This meant that I could trigger the issue with any large network
transfer, it wasn't restricted to Samba.  I'd look down this path
first, as it's pretty uncommon for Samba to be capable of locking up
the entire machine.
