I'm working on a FreeBSD 6.1 machine and setting up MySQL 5.0 with
some InnoDB tables.
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 SIZE RES STATE C TIME WCPU
COMMAND
871 mysql 8 20 0 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?
Thanks-
Thaddeus
