tux on 2.4.27 kernel and referrer checking

[joe]

I define stable as how a given kernel performs day in and day out in 
actual use on a busy server. Ironically, I moved to the 2.5 test series 
awhile back because our trusty redhat 8 firewall kept locking up at 
random, and replacing the vendor supplied 2.4 kernel with a late 2.5 
series test kernel actually stabilized it.

I have been deploying suse servers with 2.6 kernels in production and 
found them to be stable - IOW the servers don't generally go down unless 
it's for kernel upgrade or hardware maintenance. There was one nasty 
problem with the hbdev virus scanner, which loads a kernel module, and 
would do nasty things to capabilities, prevent bind from starting, and 
hang the system if you tried to shut it down - I chalk that up to bad 
code, and use clamav instead. Otherwise the 2.6 systems I've deployed 
seem to be rock solid.

I also found fedora core with 2.6 to be stable as well - I tried the 2.6 
version of tux, and it did not perform all that well, so I have not 
really done much with it since, as the general kernel improvements have 
caused apache performance to come into the acceptable range.
