I've been seeing high server loads on my wordpress site all day today, on a four core, 8gb ram, server, up to the 40's sometimes. No serious traffic to cause this.
Running 'top', I get this:
For swap, I get:
Swap: 0k total, 0k used, 0k free, 3246260k cached
That 0k total... that shouldn't be 0, should it?
I was a victim of the 'soaksoak.ru' problem that quite a few wordpress sites experienced yesterday. I found it early and replaced the effected files. They have remained clean. I've run a number of scanners and no additional malware/viruses have been found on the site.
No unusual broadband spikes on my graphs, but there have been several high spikes on the 'disk' graph.
Any thoughts on the swap thing, what might be going on, and what I might do about it?
PS: load headed up again, here's what it looks like now:
oh... just found out that servers with solid state drives don't have swap. So that's not related... any other ideas.
