    Please add relevant info from mysql's error log file. – Paul Jan 8 '11 at 19:24

when you change the innodb_buffer_pool_size size you need to remove the ib_logfile's usually located in /var/lib/mysql/ib_logfile0 /var/lib/mysql/ib_logfile2 etc. This way mysql can regenerate the pool files when you restart it.


We need more information so we can help you. Pasting what is inside the MySQL error log (usually /var/log/mysqld.log) is a great start. Also how much RAM do you have in your system? Also pasting your current /etc/my.cnf settings will help as well.
