Saving memory

Since I have been having problem with what appears to be a memory leak, I have been taking a look at what has been taking all of the memory. I create a cron job that every five minutes gets the status of the computer. It is running the following command.

ps -auxw; cat /proc/meminfo

I don't have a monitor connected to this computer, but I do run a vnc server.  This had been configured to start KDE.  I changed the window manager for this vnc server to fvwm.  This is a window manager that is smaller than KDE.

I also changed the number of requests that each apache thread can handle before it quits to 25. And, I went through the modules that had were included in apache, and removed ones that I didn't need.  I removed these modules:

mod_auth_mysql

mod_auth_anon

mod_auth_dbm

mod_cern_meta

mod_expires

mod_headers

mod_unique_id

mod_usertrack

mod_unique_id

mod_imap

mod_speling

mod_proxy

mod_proxy_ftp

mod_proxy_http

mod_proxy_connect
