Memory and CPU usage suddenly jumped after v-update-sys-rrd crash?

[viraladmin]

So last night, ./v-update-sys-rrd seemed to have some sort of problem on my server and a ps ax - showed about 50 instances of the file running for over 2 hours. So I rebooted my server. (i manually ran it after reboot and it ran fine)

Directly after rebooting, my memory usage and load averages started jumping. I have the resources to handle things, but I know that the memory and cpu usages are now running very high which is alarming.



This particular server is only running 1 website. It gets around 30,000 visits a day and uses around 1.5 TB in bandwidth a month, so "higher than normal" is typical, but mysql using 8500 MB is not typical. Spam assassin seems to just mirror whatever mysql says.

I am also fairly sure fail2ban should not be using 951 MB. I have checked the mysql logs and see nothing unusual. I have checked the iptables bans and they only list 18 reject policies in place by fail2ban. All the rules are default.

Perhaps its just me, but all the usage being showed in this screenshot seems a little off.

I am wondering if anyone might have some recommendations as to what I should check out to get the memory and loads back down to normal.
