Hello i got a wordpress site http://www.flippish.com. I have some problems with my server coz it keeps on dying around 1-2 hours after i reboot apache then restarting by itself i think thats its because of apache settings i have it on MAxclients: 2000 ServerLimit : 2300. Im really not knowledgeable on this area my RAM is on 8GB how, the site is having too much load, do i have to upgrade ram for this site?

This is my top command

  • I'd investigate why mysql uses cpu : slow queries? Also why is there 5% of iowait? iotop will show you if it is caused by mysql –  May 26 '13 at 18:10
  • Are you doing any caching? If so, look into one of the many wordpress caching plugins, as they will likely reduce your load significantly. – EEAA May 26 '13 at 18:11
  • Yes im using wp_super cache already. So its because of mysql? I have this for getting the queries 61 queries. 0.483 seconds. – Jayson Pimentel May 26 '13 at 18:13

Your maxclients setting is quite high. If you actually had 2000 clients hitting your site, what would you expect the RAM usage to be? Would that push you into swap?

Try lowering your maxclients setting.
