firewall/router crashing

[Daniel Kleine-Albers <dka@dka-edv.de>]

Hello,

i have a problem with my router/firewall. It crashes after a few hours 
of usage without a reason. When it has crashed, i'm not able to login on 
the console nor via ssh (to check the running processes, etc.), but it 
is still pingable. I looked in all the logfiles, but couldn't find 
anything unusual. The last thing the box does, is trying to dial my 
provider via pppd and the capiplugin. And before the connection is 
completely established, the logs stop and continue at the next boot 
(pressing the reset-button).

The configuration:
debian testing
ppp with capiplugin (dial on demand)
hylafax with capi4hylafax
postfix
2.4.12 kernel

Any suggestions ??
