I'm running MySQL 3.23.42 on a PIII 866 with 1 Gig of RAM. If I connect 400
requests and and ask for something all at the same time, MySQL spawns many
child proccess (hundreds and hundreds). As a result of all these processes
the system essentailly hangs (Loadavg of 588 525 310)
Does anyone know how I can stop this from happening?
Thanks so much.
