Hi, I sometimes get this message emailed to me "LiteSpeed Web server cpanel.xxx.com on cpanel.xxx.com restarts automatically to fix 503 Errors" This email occurs when I run some indexing software (not on the same machine as litespeed) that requests lots of pages from the server. It downloads about 10,000 files / hr. I have recently upgraded from a 2 to a 4 cpu license. I've got 4 cpus for litespeed to work with. When I go to my web server and look at the load in 'top' its getting up to 8 at peak periods. This is about the same performance as when we had a 2 cpu license. I think its around this load that I receive the 503 error emails. I think its utilising all 4 cpus. In Cpanels 'Process Manager' I see 5 x litespeed (lshttpd) If I go to litespeeds 'realtime log viewer' the average amount of requests / second is about 150 and the average amount of requests in-processing is about 30. Is this too much for my setup of litespeed to handle? What can I do to help it out?
