Funny that the mysql log file is clean but you are still seeing the errors in the GUI.
Let's restart everything and try again.

Code: Select all

    service nagios stop
    service npcd stop
    service ndo2db stop
    service nagios stop
    killall -9 nagios
    service cron stop
    service httpd restart
    service mysqld restart
    service ndo2db start
    service npcd start
    service nagios start
    service cron start
Wait a few minutes and login. Post any errors.

Before running the following command to repair the corrupt table, make sure you have a backup of the system.
This repair command could do more damage than good, so be warned.

Code: Select all

echo 'repair table nagios_hoststatus use_frm;' | mysql  -t -u root -pnagiosxi nagios

Oh jeez, that sounds...interesting. K, config backup from last week is there as well as one from a couple days ago. I also had our VM admin take a snapshot, so here goes nothing...
