Hi,
I have build an Apache instance 2.2.15 with prefork MPM and most of the modules as shared. I have PHP and MYSQL installed and configured on this machine (MYSQL client) with this every process created by Apache daemon consumes 280M memory almost for each call.
I am running on RHEL 5 with 5 Gig of memory when load increases on server it takes down the machine. Also I could see each library getting called thrice makes the HTTPD daemon heavy weight.
Please advice how could I trim down the memory consumption by each process.
