I have about 15 mysqld processes running. They all appear to be child processes of one. Can I limit the number of child processes of MySQL?
Here is the list of processes running: root 9505 1 0 10:19 ? 00:00:00 /bin/sh /usr/bin/mysqld_safe --datadir=/var/lib/mysql --pid-file=/var/lib/mysql/vottrt1.vistar.ca.pid mysql 9698 9505 0 11:42 ? 00:00:00 /usr/sbin/mysqld --basedir=/ --datadir=/var/lib/mysql --user=mysql --pid-file=/var/lib/mysql/vottrt1.vistar.ca.pid --skip-locking --socket=/var/lib/mysql/mysql.sock mysql 9699 9698 0 11:42 ? 00:00:00 /usr/sbin/mysqld --basedir=/ --datadir=/var/lib/mysql --user=mysql --pid-file=/var/lib/mysql/vottrt1.vistar.ca.pid --skip-locking --socket=/var/lib/mysql/mysql.sock mysql 9700 9699 0 11:42 ? 00:00:00 /usr/sbin/mysqld --basedir=/ --datadir=/var/lib/mysql --user=mysql --pid-file=/var/lib/mysql/vottrt1.vistar.ca.pid --skip-locking --socket=/var/lib/mysql/mysql.sock mysql 9701 9699 0 11:42 ? 00:00:00 /usr/sbin/mysqld --basedir=/ --datadir=/var/lib/mysql --user=mysql --pid-file=/var/lib/mysql/vottrt1.vistar.ca.pid --skip-locking --socket=/var/lib/mysql/mysql.sock mysql 9702 9699 0 11:42 ? 00:00:00 /usr/sbin/mysqld --basedir=/ --datadir=/var/lib/mysql --user=mysql --pid-file=/var/lib/mysql/vottrt1.vistar.ca.pid --skip-locking --socket=/var/lib/mysql/mysql.sock mysql 9703 9699 0 11:42 ? 00:00:00 /usr/sbin/mysqld --basedir=/ --datadir=/var/lib/mysql --user=mysql --pid-file=/var/lib/mysql/vottrt1.vistar.ca.pid --skip-locking --socket=/var/lib/mysql/mysql.sock mysql 9704 9699 0 11:42 ? 00:00:00 /usr/sbin/mysqld --basedir=/ --datadir=/var/lib/mysql --user=mysql --pid-file=/var/lib/mysql/vottrt1.vistar.ca.pid --skip-locking --socket=/var/lib/mysql/mysql.sock mysql 9705 9699 0 11:42 ? 00:00:00 /usr/sbin/mysqld --basedir=/ --datadir=/var/lib/mysql --user=mysql --pid-file=/var/lib/mysql/vottrt1.vistar.ca.pid --skip-locking --socket=/var/lib/mysql/mysql.sock mysql 9706 9699 0 11:42 ? 00:00:00 /usr/sbin/mysqld --basedir=/ --datadir=/var/lib/mysql --user=mysql --pid-file=/var/lib/mysql/vottrt1.vistar.ca.pid --skip-locking --socket=/var/lib/mysql/mysql.sock mysql 9707 9699 0 11:42 ? 00:00:00 /usr/sbin/mysqld --basedir=/ --datadir=/var/lib/mysql --user=mysql --pid-file=/var/lib/mysql/vottrt1.vistar.ca.pid --skip-locking --socket=/var/lib/mysql/mysql.sock mysql 9709 9699 0 11:42 ? 00:00:01 /usr/sbin/mysqld --basedir=/ --datadir=/var/lib/mysql --user=mysql --pid-file=/var/lib/mysql/vottrt1.vistar.ca.pid --skip-locking --socket=/var/lib/mysql/mysql.sock mysql 9710 9699 0 11:42 ? 00:00:01 /usr/sbin/mysqld --basedir=/ --datadir=/var/lib/mysql --user=mysql --pid-file=/var/lib/mysql/vottrt1.vistar.ca.pid --skip-locking --socket=/var/lib/mysql/mysql.sock root 9804 9763 0 11:53 pts/1 00:00:00 grep mysql

sorry not answering your question.that was normal, it is a child process. when mysql get more request, it will create a child process to handle the request.
