The DB record for Kavehost is missing in Watchdog
INSERT INTO `psa`.`module_watchdog_service` (
`id` ,
`name` ,
`label` ,
`sort_val` ,
`mon_status` ,
`save_stats` ,
`timeout` ,
`timeout_restart_num` ,
`timeout_cycles_num` ,
`connection_timeout` ,
`start_cmd` ,
`stop_cmd` ,
`start_time`
)
VALUES (
NULL , 'kavehost', 'KA Anti Virus', '10', 'monitored', 'on', 'on', '5', '5', '5', '/etc/init.d/kavehost start', '/etc/init.d/kavehost stop', '60'
);
And watch dog will work again... i had this same problem too.
