I have a problem about the innodb memory usage. The following is my config file for mysql and the version I am using is 4.0.12 in FreeBSD 4.7 stable.
my.cnf
[mysqld] port=3306 datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock set-variable = thread_cache_size=700 set-variable = table_cache=1000 set-variable = key_buffer_size=16M set-variable = max_connect_errors=9999999999 set-variable = max_connections=850 skip-name-resolve skip-locking memlock
####### INNODB CONFIG ####### innodb_data_home_dir = /var/lib/mysql/innodbdata innodb_data_file_path = datafile:4096M:autoextend set-variable = innodb_buffer_pool_size=24M set-variable = innodb_additional_mem_pool_size=8M innodb_log_group_home_dir = /var/lib/mysql/innodblog innodb_log_arch_dir = /var/lib/mysql/innodblog set-variable = innodb_log_file_size=10M set-variable = innodb_log_buffer_size=8M innodb_flush_log_at_trx_commit=0 #############################
[mysql.server] user=mysql basedir=/usr/local/site/mysql
[safe_mysqld] err-log=/var/lib/mysql/mysqld.log pid-file=/var/lib/mysql/mysqld.pid
When I start the mysqld, the memory usage is about 85M. Then the mysqld will use more and more memory and doesn't release. It will use all the memory and the performance will be dropped when it starts to use swap space... Do anyone know how to calculate the memory mysqld use when it starts? And also any method can be used to limit the memory usage for innodb? I don't have memory problem when using MyISAM before... The memory usage of mysqld reachs certain level and will not continue to grow.....
Thanks a lot.
Kaming.
