Unable to drop tables in MySQL

Technology: 16 Jun 2004, 06:00

This is as annoying as heck. And unrepeatable to boot. Anyone have a suggestion about how I messed up my installation?

8:08 AM: seems to be related to the suid script that I use to run mysqld_safe. If I run the script as the mysql user or I explicitly run /usr/local/mysql/bin/mysqld_safe as myself, then everything is fine. But when I run the suid script as myself, then the problem appears.
