Check_MK Werk 6342: Fixed degraded SNMP check performance when using SNMP sub checks

ID: 6342 Title: Fixed degraded SNMP check performance when using SNMP sub checks Component: Checks & agents Level: 2 Class: Bug fix Version: 1.6.0i1 When checking a host with SNMP sub checks which normally all get the same data, the data was fetched multiple times. One time for each subcheck used for monitoring a host. This resulted in significantly increased check times and time outs. All 1.5 versions are affected by this issue. We experienced this issue with a CMCiii device which is normally monitored by a set of sub checks (cmciii.*).
