Hi, >From previous message (I don't run linux), I believe that linux ps lists all threads, and mysqld does create a thread for each connection.

Each time I open a database handle (in perl code), does that cause a new process to run, a new instance of mysqld? And each time I disconnect the database handle ($dbh->disconnect() in perl code), does that cause the number of running instances of mysqld to go down by one? The process list on my Linux server includes several instances of mysqld: server1:/home/bhaselto/web/html$ ps auwx | grep mysqld root 1014 0.0 0.0 1672 0 ?

R 21:07 0:00 /usr/sbin/mysqld --basedir=/ --datadir=/var/lib/mysql --user=mysql -- so I was wondering if that was the explanation -- I know I have multiple running scripts that use the database at the same time, although I thought they generally didn't leave the handles open that long. -Bennett [EMAIL PROTECTED] http://www.peacefire.org (425) 649 9024 --------------------------------------------------------------------- Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
