apache in worker mode eats memory

[Mark Bojara]

Hi All

Im running Apache 2.0.53 server on 5.4-RC3 AMD64 in Worker mode. This webserver serves 50000 hits per hour. Whats currently happening is it works fine for 8 hours then the server just starts spawning httpd processes when it reaches about 70 processes the box runs out of memory and swap space then crashes :(

This is what I currently have set: 
ServerLimit             16
StartServers            2
MaxClients              150
MinSpareThreads         25 
MaxSpareThreads         75   
ThreadsPerChild         25
MaxRequestsPerChild     20000
EnableSendfile Off
HostnameLookups Off
EnableMMAP on
Timeout 120
KeepAlive On
MaxKeepAliveRequests 1024
KeepAliveTimeout 15

Anyone seen this perhaps a better way of doing it?

Thanks
Mark
