MySQL connection overload - what is causing it?
A few sites on my server rely on each page request connecting to MySQL. I know it's not perfect but for things like vbulletin there is no alternative.
Recently there were lots of too many connection issues, so I increased the number of simulatenous connections from 500 to 1500 (which is way to much imho). There is no way legitimate traffic is causing anywhere like this amount. It must be robots or scripts going wrong.
How can I find out which it is?
