These are my specs: A dedicated Intel Xeon 8CPU box, 8GB RAM on centos 6.5 For the last 2 days my server has been going down every 30 minutes or so, and I'm trying to find out why. So far no luck. Here is my setup: PHP suEXEC max conn: 5 Max connections: 2000 Connection timeout: 300 Max keep-alive requests: 100 Smart keep-alive: Yes Keep-alive timeout (secs): 10 LS External App Max connections: 400 Environment: PHP_LSAPI_MAX_REQUESTS=3000, PHP_LSAPI_CHILDREN=400 Initial request timeout: 60 retry timeout: 0 Persistent connection: No Connection keep alive timeout: 60 Response buffering: No Instances: 1 My website is fairly busy, but I've noticed this happens when the site visitors exceeds 250, as during off peak hours everything is okay. Can anyone help please. Am using Litespeed Enterprise v4.2.12 Thanks.
