If you have not yet tried it, install a copy of 'htop' from Dag Wieers' SourceForge repository. There is an el6 version of the repo configuration rpm available at: packages.sw.be/rpmforge-release/ 'htop' is an excellent tool for poking around processes, and allows you to scroll vertically *and* horizontally through the process list. I much prefer it to traditional 'top'. Chuck
