Re: Re: "Out of memory; check if mysqld or some other process uses all available memory;" error

Hi Mathieu,  

I found that innodb_buffer pool value isn't set..The whole innodb settings are commented.

I found the below values from the my.cnf file:  

# Uncomment the following if you are using InnoDB tables

#innodb_data_home_dir = /var/lib/mysql/

#innodb_data_file_path = ibdata1:10M:autoextend

#innodb_log_group_home_dir = /var/lib/mysql/

Do you need help?

#innodb_log_arch_dir = /var/lib/mysql/

# You can set .._buffer_pool_size up to 50 - 80 %

# of RAM but beware of setting memory usage too high

#innodb_buffer_pool_size = 256M

This looks like the traditionnal 32 bits limitation ... You're using a 32 bits system right ? Because of many reasons (lots of documentation on

the net about that) MySQL is in practice limited to about 2.4-2.6G of memory, thus the error you see.

When I experienced this errors, I lowered the mysql_buffer and innodb_buffer so that mysql would stay below this limit and never had other issue with it. (It was crashing with an error 11 before). I kept this settings till I could upgrade to a 64 bits host.
