Seems to be an old bug inherited from Nagios (http://osdir.com/ml/network.nagios.devel/2004-05/msg00003.html): When a service dependency tells a service to stop checking in dependence of another check satellites happily obey this command. The master, however, finds out that no check results are being delivered by the satellites, and finally sets in with freshness checks, completely ignoring the service dependencies.

This is really bad in cases when the dependency is defined in order to prevent hanging check procs to pile up on the monitored host. Disabling freshness, on the other hand, is no issue as the master should take over checks in case a satellite is failing to check or to report.

I partly understand the issue, but I don't think there's an easy solution for that. Either disable freshness checks on the master, or fix the freshness code taking dependencies into account. For the latter I am not sure how much impact this one has (patch, tests, changes?).
