Checkmk Werk 12705: Fix "Checker and fetcher mismatch" for SNMP devices that cannot be resolved

ID: 12705 Title: Fix "Checker and fetcher mismatch" for SNMP devices that cannot be resolved Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0i1 The service Check_MK Discovery could produce a crash report with the error "Checker and fetcher mismatch" if the address of an SNMP host cannot be resolved. Alternatively, the service would be OK although the host was not checked. Now, the service for the unreachable host will fail consistently (CRIT) with the error: "Host has no IP address configured".
