Re: Memory usage for MySQL
From what I read you should only change kern.maxdsiz, changing kern.dfldsiz makes every process allocating this amount of memory by default, thats bad. Something like: kern.maxdsiz="1395864371" # 1.3GB #kern.dfldsiz="1395864371" # 1.3GB #kern.maxssiz="134217728" # 128MB would do the trick for you, check limits also and see what the init scripts may be limiting on this process.

The machine has 2GB of RAM and will primarily be used as a database machine and will also be serving files over NFS (not high volume). The issue that I'm having is that when I start up MySQL I get a couple "Out of Memory" errors before it actually starts up. Looks like this- 060719 11:55:35 InnoDB: Started; log sequence number 0 43656 /usr/local/libexec/mysqld: Out of memory (Needed 950109184 bytes) /usr/local/libexec/mysqld: Out of memory (Needed 712581120 bytes) 060719 11:55:35 [Note] /usr/local/libexec/mysqld: ready for connections. Version: '5.0.22-log' socket: '/tmp/mysql.sock' port: 3306 If I reduce or increase the innodb_buffer_pool_size variable for MySQL I can eliminate or increase the number of errors. This set of errors was with innodb_buffer_pool_size set to 600M This is what top currently shows for MySQL- PID USERNAME THR PRI NICE SIZERES STATE C TIME WCPU COMMAND 871 mysql 8 200 1196M 159M kserel 0 0:01 0.00% mysqld I tweaked /boot/loader.conf to allow larger data size for processes already (rebooted after changes)- kern.maxdsiz="1395864371" # 1.3GB kern.dfldsiz="1395864371" # 1.3GB kern.maxssiz="134217728" # 128MB If there's an out of memory error, how come MySQL starts up? Is this something to be concerned about? What else should I be checking to figure this out?
