It shows the processes using the most cpu (by default. You can also display by io.) So, if mysqld isn't using a lot of cpu, it's not going to show up in the list. You might be able to force it to show up by giving top a number (of processes you want to see) that includes enough that mysqld will show up. -- Paul Schmehl, Senior Infosec Analyst As if it wasn't already obvious, my opinions are my own and not those of my employer. ******************************************* Check the headers before clicking on Reply.
