Here is the pstree result. (Both of > them runs the same version of mysql) Mysql uses threads and doesn't fork off several processes to do the work. Older kernels (or - the older threads version in Linux) show each thread as a new process with its own pid. Recent kernels and pstools just show the pid - so you're not able to see the threads mysql has spawned. You can see those threads with ps, using the "-m" option (show all threads): ps aux -m | grep mysql Regards, Ralph -- Ralph Angenendt......ra@xxxxxxxxxxxx | .."Text processing has made it possible Bayerischer Rundfunk...80300 München | ....to right-justify any idea, even one Programmbereich.Bayern 3, Jugend und | .which cannot be justified on any other Multimedia.........Tl:089.5900.16023 | ..........grounds." -- J.
