a very busy server , nice
(adsl/atm , firewall ...wireless...
)
anyway, i love challeges, if you have enought patience we could try another thing :
compile under root please .
before lunching the compilation, can you throw in a loop in another shell / terminal that dumps a ps -edf or ps aux to a file , and at the end of the script (the loop) do a sync , etc ...
like
while true
do
ps -edf > /tmp/mylog.txt
sync
sleep 1
done
there is another like sleep command that takes shorter delays than a second, if u can find it , a half second would be even better
so when the server crashes, the file should be on disk,
I know this is hardcore but hell , that's how we discover things, and as you said you might reinstall it anyway .
after the crash (sorry !!! ) that file will contain the answer
