This might help with that task: mysqlbinlog binary_log_file_name.000001 --start-datetime="2013-02-25 16:45:00" --stop-datetime="2013-02-25 16:50:00" | grep 'DELETE\|ALTER TABLE\|PARTITION'

If they are, look for anything that may remove data from a table like DELETE commands or ALTER TABLE ... PARTITION ... commands (dropping or resizing your partitions) If you haven't already, verify in your error log that your MySQL isn't being randomly killed by your OS for exhausting its RAM. If those are both a bust, enable the General Query Log and see if any other weird commands you don't recognize are being sent to your database. http://dev.mysql.com/doc/refman/5.6/en/server-logs.html -- Shawn Green MySQL Principal Technical Support Engineer Oracle USA, Inc. - Hardware and Software, Engineered to Work Together.
