Hi Tom

I havent heard of any similar issue so it would be great if you could
add it to the jira so it can be tracked.

Are all builds triggered by a SCM change? You can tell by looking at
one of the builds page, and if it says "triggered by SCM".
Are the jobs built on the same machine?

The build is started either because the workspace is invalid (or not
present on the machine) or if there has been a commit during a period.
Newer Hudson versions store the SCM polling log together with the
build (if it was started by a SCm change), so hopefully we can get
some info from that. To see the polling log for a certain build, go to
the Build page, click on the "Started by a SCM change and you should
see the full log. (similar to
http://ramfelt.se/job/Mockito/528/pollingLog/?)

If you dont have a link for the SCM change then you will have to
manually watch the SCM polling log just after you reboot your server
to see why the plugin triggers a new build.
