A host has discovered a set of check plugin names which are triggered by the Check_MK service. If the agent type of this host changes without performing a rediscovery afterwards and the configuration changes are activated then there may be new or vanished check plugins which are unknown to the current check context. This leads to a KeyError of the Check_MK service.
Now if a check plugin is unknown to the current check context Check_MK ignores this check plugin. Aside from that the Check_MK Discovery service reports about vanished or unmonitored serices.
