If it's a commercial server and it's load under the 40%
it's easy, buy a disk and build a chrooted gentoo with hardened-dev-sources
then schedule a downtime of some hour to make the change.
Before to do this anyway it's better to figure out what really is the
problem, try to isolate it,
reboot, cat somewhere that output of "top -b -n1" and diff one hour
after and one day after,
try also "ps ax -eo user,vsize,size,command" and "man ps" I bet you will
find what is strange
btw 2.4.27 it's *not* an old kernel.
