i host about 4 sites which are of multiple domains on single account. my site traffic is not that good exect i get about 3000 uniques for about 2 sites and the rest about 1000 uniques per month. my bandwidth never crossed 2gb monthly. i was going nuts when my host informed that the server CPU is running about 100% causing about 100+ domains go down. I really couldnt find out where the problem lies. I have the following suspects in my list, for pulling the server down 1. Modrewrite .htaccess (i use it for all sites) 2. phpbb2 forum (fully customised) 3. Faulty php script (thinking of recursive function) what could really cause such downsize? i dont think i have any problem with mysql queries or server.
Sounds like a dodgy script to me. If you ask your host they should be able to tell you which page is causing it.
i already have a new host, as new host is not issue here. i am really curious what went wrong with scripts. if this is the problem, it might happen with new host as well. does anybody have any experience for killing the CPU?
Could be a compromised script. Look for files you don't recognize. A spammer could be using one of your sites to spam thus maxing out the server.
nope! i used custom coded script. i really suspect phpbb2 since i had plenty of mods added it. still couldnt figure out though!!!
