ID: 14689 Title: Fixed various Livestatus columns in the NEB Component: Livestatus Level: 1 Class: Bug fix Version: 2.2.0i1 Accessing some Livestatus columns via the NEB could potentially lead to a crash of the Nagios core. This affects the "service_period" column in the "hosts" or "services" tables, or the "filename" column in the "hosts" table. This has been fixed. If you are running the CMC as the monitoring core, you have not been affected by this bug.
