I have a page, where every user makes Ajax request every second. If there are many users on the site, everything freezes and server needs to be restarted. How should I configure httpd.conf (KeepAlive etc..)? I know that it's possible, because there are several similar sites.
Hi starfet, What value do you have for MaxClients? If it is too low like 128 then that is probably the issue. Raise it to 512 or 1024 then restart apache. This may help you: http://forums.theplanet.com/index.php?showtopic=90598
The page is on a VPS. If I increase MaxClients, the kmemsize will become full and VPS will freeze. So I guess only solution is to ask service provider to increase max kmemsize or move to another server? (CPU and RAM usages are normal when the VPS freezes)
