Mysql has failed, please contact the sysadmin

You Must be getting this error wile starting SQL from WHM (Mysql has failed, please contact the sysadmin). When you try to restart SQL server from SSH you will get something like this (Starting MySQL... ERROR! The server quit without updating PID file (/var/lib/mysql/zeus.domain.com.pid).)

This likely indicates that native AIO support is not enabled on the server

The fix is very Simple

Add innodb_use_native_aio = 0 to /etc/my.cnf and MySQL should then restart successfully

Hope it Helps...!!!
