Greetings, everyone. We've recently started having all sorts of nasty problems at our drupal installation at http://armchairarcade.com/neo. We have the latest 4.7 drupal installed with image and img_assist (all latest versions).
Anyway, one of the recurring problems is that some (not all) of the images fail to show up in the blog posts on the frontpage (or sometimes even in the blog post dedicated pages). It seems virtually random how many and which ones actually show up. Sometimes none of them show up. Everyone seems to have this same problem, whether they're using FF, IE, or Safari. I've tried and tried to find this glitch but can't do it.
Another far more serious problem is that lately our site has been suffering from a mysql error--"maximum connections reached." This is inexplicable because we have NOT enjoyed a increase in participation, and the webstats at cpanel indicate that we're receiving about the same # of hits as always. We've tried throttling drupal and banning ip's that generate too many hits on our site, but that doesn't seem to affect the situation. Last weekend, we could barely access the site because we kept getting these errors (this is through modhost).
Modhost suggested that Drupal (or a "rogue module") might be a "resource hog," but again, I don't see why we'd suddenly be getting all these errors.
It may be a coincidence, but we have a script kiddie who launched a DoS attack on another website recently and brought it to its knees. "Bigchris" is on our website now (at least, he made a forum post), and we have reason to believe (but no hard evidence) that he's somehow responsible for this. Could there be a connection? If so, what, if anything, can we do about it?
