Hello David,

This bug is the result of some recent optimizations. The database requests updating the build statuses are queued and issues by batches of 100 requests. As you only have 10 builds, those requests are only queued. That's why the web interface reports them as "scheduled" while the log shows that they were built. The "fail: 10" is also a consequence of that problem. Forcing the pending queries once a batch of builds is done could possibly solve this problem but I need to think more about it. Thanks, Mathieu
