Cannot set innodb_buffer_pool_size without mysql crashing (2 replies)

Hi

I have a 32bit centos 5.8 server running mysql 5.0.95

If i try and set the innodb_buffer_pool_size the mysqld service will not start.

I would like to set it to 4G but even if i try 512M the service still crashes.

Below is my copy of the my.cnf

thanks

Tim
