Hah. I suspect the machine was running when it crashed - that is, the mysql was shut down uncleanly? You can safely ignore the mysql.plugin bit for the moment - that's for when it's booted properly. It looks like the newer InnoDB has trouble reading your ibdata file. Possible causes: * Are all

My Apologies, The tables are all MyISAM, most of the inserts/updates/deletes are done through stored procedures on the master. There are about 2 stored procedure calls per second, consisting of a whole bunch of queries, updates, and inserts within them. The latest issue(s) we're having, are: Co
