Hello! Im having a bit of isssue with a 2GB linode that i cant seem to wrap my head around. I have a friend's wordpress site that gets about 3k pageviews a day. it's basically a blog. I've installed supercache and all that jazz. Yet every hour or so, the server hangs. (It appears to MySQL as disabling that brings the sites online - except for a cannot connect to database error.. in other words, static stuff appears to be fine) During this time, I'm often seeing a spike in MySQL memory. Rebooting the server doesnt really do anything either - oddly. Eventually, it fixes itself and everything moves fast.

The server is running Ubuntu 10.04 LTS 32 bit, php5-fpm/fastcgi, MySQL 5.1.7, memcache
Before i stuck the friend's blog on here, CPU was sitting at a cool and constant 5-10% on my own drupal sites.
Root login is disabled (using ssh keys)
I've changed php5-fpm to ONDEMAND from DYNAMIC. I can post config files if needed too.

Oddly, php5-fpm process appears to be spikng more on average than mysql.. though i see the latter spiking too.





My mess of a my.cnf file:

any help would be appreciated! Also bear with me since Im not exactly the best at all this stuff either. Thank you!

Ubuntu 10.04? Time to replace your sever, support for that server expires on the 30th April. Replace the server with Ubuntu 14.04 and see if your problems go away.

How to ask for help
1. Give details of your problem
2. Post any errors
3. Post relevant logs.
4. Don't hide details i.e. your domain, it just makes things harder
5. Be polite or you'll be eaten by a grue

yeah it's been on a long list of things to do. Anyone know how hard it is to migrate?

Server loads seem a little bit better when i blocked the xmlprc file but seems to be going up and down still.
