>Due to an SCM polling bug that was introduced in Hudson 1.353, we have upgraded the build machine’s Hudson instance to 1.354 which fixes this bug. If you still notice polling issues, then please provide feed back on bug 309295.
In addition, to help reduce the load on the various SCM servers we use, I have set a thread limit of 10 concurrent polling threads at a time. Before it was unbounded and as the number of jobs has grown the thread count was increasing dramatically. If we need to increase this number we can do that as well.
One nice thing about upgrading hudson lately, is that it makes if very simple to do. Just press a button, and it downloads and installs the latest version. A restart later and the new service is up and running.
