It could be the size of your InnoDB log files.  Or something else which 
stops InnoDB running.

I once changed server and by mistake changed the size of the 
innodb_log_file_size.  The result was that InnoDB could not start and 
instead dissabled its self.  Therefore every table I created became MyISAM.

Check the error.log.  If this is the case it will say....

Also do a SHOW ENGINS, may show something...
