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

# ps xeo "command wchan" | grep lilo

I have a server running 2.2.17 + raid-patches from
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 ?


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:
