I get this problem about once a week.

In order to resolve it, I stop Nagios, stop NDO, restart mysql, drop the
Nagios database, recreate the Nagios database, start Nagios and start
NDO.

Once done everything works again. If I don't restart mysql I cannot drop
the Nagios database within the mysql client and sometimes I need to
expressly kill (-9) both Nagios and Mysql.
