Hi,

has worked FINE for months. The other day, the client rebooted it. They
shut it down properly and then later started it up again. (The server
was not experiencing any problems when they did it, there were other

Try
show table status
or
select table_name,create_time from information_schema.tables

I would have said to look at the creation date of the .frn file, but there
is also a field called create date in the show table status command and

The create date in show table status is metadata held in the table
itself wheras the create data on the .frm file is when that file was
created - i.e. if you copy the data files (without preserving
attributes) it will have a new creation date on the filesystem but the
metadata of the table will

Just looking over the server status, it looks

If you have the slow query log enabled, grab some
slow queries from there and run EXPLAIN.
