Hi,

Recently I've upgraded Jenkins to ver 1.508 and many plugins (including Jenkins GIT plugin from 1.1.25 to 1.3.0) and since that time I got a lot of my jobs using Git SCM running very frequently without any reason.
None of my jobs using "Poll SCM" in "Build Triggers". But I see them running with build cause "Started by an SCM change" though very often there are no changes at all. And Polling Log is always empty.
