We upgraded our server from 10.3 to 10.4.2 in July and everything was running great then we started to get an error that no one can quite seem to help with:
Aug 30 11:42:28 www cyr_expire[4576]: DBERROR: mydelete: error deleting : DB_NOTFOUND: No matching key/data pair found

As you can see from the time stamp the system creates large log files with this message and the CPU's max out at 100%. The temporary fix is to stop/start the mail service which is usually good for about 12 hours.
Apple has offered little support for this, if anyone out there knows a fix please let me know. thanks
