Server load strangely high these days! Here is my info.. (Help pls..)
- This is a VPS account on Servint.net (512MB ram guaranteed)
- I've done tweaks on my httpd.conf, my.cnf, etc a month ago under some suggestions of my server provider, and stopped a lot of unneeded services in my WHM, like mailman, spamassist, etc.
- Visitors of my website hasn't really increased these days
- I didn't do anything to my scripts and the server configuration.
- It started to show as high load (Some times over 22!!) when I type 'uptime' since 1 week ago.
- I have only my site with Invision Power Board on my VPS, the online users are 50 within 15 minutes.
- High load not happen all the times, it happens like every 5-15 minutes or even longer, other than that the load is quite normal as before: 0.3-0.6 , although there are 50 online users all the time. And it happens even when there are only 8 users in the night.
- I've checked with 'netstat -an' and I can find 10-15 SYN_RECV.
'uptime' now gived output:
