An interesting bug in RHEL 3(which affects CentOS 3) has been 
bantered around for a while.  There are some kernel 
patches(beyond my scope right now) or some echo statements tht 
are used(this helped my situation).  The newest 2.4.x kernels 
have these patches incorporated.  Would centOS 3 go nuts if i 
installed the latest kernel from kernel.org?

<btw the issue is that the 2.4.xx kernels ahve a tendency to fill 
up ram with cache..which is normal.  The bug is that the kernel 
then refuses to rlease the cache and instead starts 
swapping...which i have noticed in my little install here.  What 
i did to fix it as a workaround(noted in the buzilla report here: 
   https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=89226
is to send the following command at the command line: (echo 1 10 
10 >/proc/sys/vm/pagecache)  I have noticed this is another RH9 
server i ahve access to and will be trying it on that box too as 
well as my linux firewall.>

Isa 54:17  No weapon that is formed against thee shall prosper; 
and every tongue that shall rise against thee in judgment thou 
shalt condemn. This is the heritage of the servants of the LORD, 
and their righteousness is of me, saith the LORD.
