On clustered services the discovery parameters are written to each individual autochecks file, but when the currently active node was not the first node in the cluster the Service discovery detected this a a changed service, even though the correct parameters have already been written to the correct nodes autocheck file.

Now, active nodes are being prioritized when detecting changed services which means this problem will no longer occur.
