[Buildbot-devel] Improper combination of changes

[Dustin J. Mitchell]

Dan's right - from what I can tell you're seeing build requests being
merged.  This feature exists so that Buildbot can shed load when build
requests arrive at a sustained rate higher than the available slave
resources can support.  As you've seen, in shedding load it also loses
potentially useful information.

I'd recommend disabling request merging (c['mergeRequests']=False).
