The PING services, which is being created for hosts which are not monitored via SNMP or agent, sometimes reported packet loss of x% while the host check of the microcore reported that the host is reachable without problems.

This issue was caused by the way the Micro Core icmpsender generated the ICMP packages. These packages seemed to confuse the check_icmp plugin which is executed by the PING service.
