we are facing a problem,that new requests are not processed even if apache hasn't reached its max_client setting.
Max_client is set to 800
max_spare server is 36
min_spare server is 35
keepalive timeout 10
Why is apache not processing new requests and sending timeouts evenif it hasnt reached its max_client value.
An strace revealed that around 80+ apache children is in idle state that is 0.0000 seconds in strace ouput.
Why this many children is in idle state and still generating new children,but stillnot processing request and sending timeout.
we are using Php5,Apache 2 with mpm-prefork,Mysql 5,Running on Ubuntu 11.04 with CSF firewall.
All the requests are made from single ip(our ip address).
Will too many request from a single ip result in any TCP/IP or Apache Restrictions to connect,result in denying new requests?
