well, it looks like we forgot to copy system.map. grr :/

# ps xeo "command wchan" | grep lilo
Warning: /boot/System.map has an incorrect kernel version.

I have a server running 2.2.17 + raid-patches from
http://people.redhat.com/mingo/raid-patches/
with adaptec aic7xxx using qpopper. It works fine.

What we realized is when the RAM is not enought (2.2.17 too)
server uses swap and the process are going to be in D state. Probably
it is normal since read/write is slower on HD and it should be
normal to not be able to kill a process writing in memory ?

Anyway

We tested this night a server on 2.2.17 (celeron/128ram/ide/intelpro)
thought apache (70 req/sec / 6-7Mbs)
After 3-4h of work server swapped and all went down.
dmesg gave:

VM: do_try_to_free_pages failed for httpd...
