My fastCgi settings are:
Instance MaxRequests: 10000
Max Instances: 0
activty timeout: 3600
idle timeout: 300
request timeout: 3600
If i set my Max instances to 40 (ie 4cpu * 10 is a suggested rule of thumb) would that prevent the number of php-cgi processes from getting out of control?
Whats the downside to setting max instances too low? When the limit is reached are users affected adversely?
Does anyone think 200 php-cgi processes should occur under normal circumstances?
