You have to decrease you innodb_buffer_pool_size = <60-80% of your main memory)

Solution for Innodb Error:

110603  7:34:15 [ERROR] Plugin ‘InnoDB’ init function returned error.
110603  7:34:15 [ERROR] Plugin ‘InnoDB’ registration as a STORAGE ENGINE failed.
110603  7:34:15 [ERROR] Unknown/unsupported storage engine: InnoDB
110603  7:34:15 [ERROR] Aborting

10603  7:34:15 [Note] /usr/sbin/mysqld: Shutdown complete

I moved the ib_logfile0 and ib_logfile01 to bak and start Mysql again. Now this time, it is working fine

[root@xxx mysql]# mv ib_logfile0 ib_logfile0-bak
[root@xxx mysql]# mv ib_logfile1 ib_logfile1-bak
