is it possible to have max connection for php set to more than 2000? my server is currently hitting over 2000 request and its causing a backlog and lots of 503 errors. I use this litespeed to track impression served by an adserver. All my connections are very small and short, I've disabled keep alive and reduce timeout to 20 seconds, attched is a screenshot of my current config. My hardware seems to be able to handle the load but litespeed is choking. I've also remove php suexec since it was limiting me at 500 concurrent connection.
