I'm not sure if it's some issue of ours--QB isn't helping me to narrow the issue down--but we appear to have some builds that have run to completion, and QB looks to be finishing everything up, but it never actually completes. What's really interesting is that a new build is allowed to start, even though QB was not finished with the previous one. We do not have concurrent builds set up, so this is kind of surprising and I'm not sure if it's part of the issue or not. I'm attaching a screen shot showing that a build is still going, but other builds have completed afterwards.
