Is anyone else getting 504's here? I seem to be getting them a lot lately. Did something change on the site? I am guessing that it is just getting more traffic these days.
Sometimes php5-fpm decides to run wild... I'll look more into it tonight, on how to prevent it from suddenly eating all the CPU up. May serve php over Apache too, as was suggested in another thread, though unsure of what all this would entail. I've set up a LNMP stack on a dev server with Apache processing PHP requests, but haven't done this on anything production nor have tested differences between the two yet.
For me, it was just something that I have noticed in the past day or two. In some ways, it is a good problem to have. It means the site is growing, and I think that we all want that to continue to happen. I am sure you will get it ironed out.
With regard to keeping the process somewhat in line, I remember @KuJoe posted a script a while back intended to run on a regular CRON:
Don't know how much help that would be if you're locking up from CPU usage, but it might tame things a little until you find a fix, or choose another solution.
