As promised I want to share the effort with you.
I developed a mechanism which loads additional service related rules to silence some IDS alerts and prevents the flooding of the log file.
As usual for development processes, I posted all details to our development mailing list, which can be found here:

In case you join testing do not post your feedback here, please do this on the mailing list.
