Hi

Im running a stock install of Slackware 10.1 with the default setup of mysql. Whats happening is when I hit the reload button several times on a page that uses php and accesses mysql I get <mysqld> defunct and zombies start showing when viewing top. I also get this when I run a web based apache bench on my server with the Requests set to 25 and Concurrency set to 5.

I checked my domains error logs and there is nothing there. I looked in the error log located at /var/lib/mysql/ano.err and here are the last few lines of it. Im new to linux so this is the only error log I could find for mysql .
