Silly questions first because they are easy to miss and can easily get you tearing your hair out if you don't check them: did you restart mysqld after changing the ulimit? Did you perhaps change PHP settings and not restart Apache? Maybe moved the sock file via change in my.cnf and not update PHP to go to the new place, or not restart Apache after changing PHP settings?

If none of those, this post might have something else which causes you to see the solution:,9127,19243#msg-19243 . More possibilities in the manual at and in this thread if you're using SELinux: .

On Fedore Core 2 and 3 I've had 2,000 connections and non-persistent connection/query rates from PHP of more than 3,000 per second, so it's not a fundamental limit in MySQL.
