It doesn't sound like a hang, more like the build completes but the process doesn't go away for some reason (not something we've seen before). Did the problem just start occurring recently, and any ideas what might have changed when it started?
One possible workaround would be to configure the step that calls the child build to terminate after some amount of time (longer than what the build would normally take).

Please send the .bld files, details on how they are launched (scheduled task, manual launch, etc.) and any other info from
