I just enabled InnoDB on my MySQL server and I’ve made the necessary changes into my.cnf. When I restarted the MySQL server I got the following error in the log:
InnoDB: The InnoDB memory heap is disabled
After some checking I’ve found that I need to set the value of innodb_use_sys_malloc to 0. After I added this entry
innodb_use_sys_malloc = 0 into the my.cnf and restarted the MySQL Server the error was gone.
