Database Error - Table Handling

[Mean]

Sir I cannot understand what he said about ?

I don't really remember what the cause of this was. Does mysqld run up to 99% and jamms up? If so, try tracking the query that takes all of the resources. I recently solved that prob by checking out slow queries of mysl. In /etc/my.cnf add the
log-slow-queries=/var/log/mysql-slow.log
set-variable = long_query_time=10
log-long-format # this will log selects not using indexes
