The machine has Redhat 6.0 installed, running kernel 2.2.5, and pppd is 2.3.10.
The relevant excerpt from /var/log/messages is:
Dec 2 08:50:51 cuttlefish modprobe: can't locate module ppp-compress-24
Dec 2 09:30:00 cuttlefish kernel: PPP: ppp line discipline successfully unregis

Dec 2 17:11:36 cuttlefish xfs: xfs shutdown succeeded

As can be seen, at 8:50, the machine connects to the net, and everything is
fine, at 9:30, the ppp module is unloaded from the kernel, yet pppd doesn't
terminate until 5:11 in the afternoon (triggered by me rebooting the machine)
whereupon it encounters various errors due to the ppp module unregistering it's
network device.
This may be (read is almost definitely) due to the server at the other end of
the line being reset at 9:30 (I don't know what it is exactly, probably a Cisco
of some flavour though, I can find out if it's important), but as I see it,
it shouldn't cause this behaviour.
Any help would be appreciated.
