We are experiencing problems on our AIX server when we are running many processes. I am not sure if it is apache related but it seemed like a good starting point. The processes generated on the AIX server will usually require access to a separate database server to retrieve data. We have demonstrated that when we run a particular application wherebye many processes of the same type are running in parallel, we find that some processes are failing when they are not expected to. If we run these processes serially we do not experience this problem. I wondered if there could be a configuration problem with apache that is causing this. I'm not that familiar with apache so I'm not sure how I can check out if it is an apache problem. I'm aware of the /usr/IBMIHS/logs/error_log file but I'm not sure how to interpret what's in it.
Also of the /usr/IBMIHS/conf/http.conf file but there are many settings in here and I'm not sure how I can check if, for example, any of the max values specified are being exceeded. Any pointers would be very welcome. I can provide more config/log info if this would help.
