I have three instances of the MySQL daemon (mysqld) running on my server. Is that normal?

If you are running linux the top command shows each thread as a process, it's a quirk of top. It's really just one instance of the program running several threads.

I see.
I also tried "ps". Here's partial output from "ps -fA", which shows the PIDs and PPIDs for the mysql stuff. So this all looks normal?
root 1 0 0 Jan05 ? 00:00:05 init
root 802 1 0 Jan05 ? 00:00:00 sh /usr/bin/safe_mysqld --datadir=/var/lib/mysql --pid-file=/var/lib/mysql/p
mysql 848 802 0 Jan05 ? 00:00:01 /usr/sbin/mysqld --basedir=/ --datadir=/var/lib/mysql --user=mysql --pid-fil
mysql 875 848 0 Jan05 ? 00:00:01 /usr/sbin/mysqld --basedir=/ --datadir=/var/lib/mysql --user=mysql --pid-fil
mysql 876 875 0 Jan05 ? 00:00:00 /usr/sbin/mysqld --basedir=/ --datadir=/var/lib/mysql --user=mysql --pid-fil

Yup, all seems fine. If anything, I would worry about the low number of processes. =]
The process owned by root is the real process, if you ever have to kill it by hand, that's the one to kill. Hopefully you should never have to do that though.

Dave, run ps -auxf You'll see something like: <br />root 8739 0.0 0.0 2140 832 ? S 2002 0:00 /bin/sh /usr/bin/safe_mysqld --defaults-file=/etc/my.cnf<br />mysql 8754 0.0 10.3 204264 160680 ?

S Jan03 0:00 \_ /usr/sbin/mysqld --defaults-file=/etc/my.cnf --basedir=/ <br /> safe_mysqld is the parent with a whole lotta children
Picture perfect penmanship here.
