[Buildbot-devel] fun race condition in old web front end for buildbot

[Thomas Middeldorp]

I've noticed when doing a reconfig (on 0.8.8) that the buildmaster will remove 
and immediately re-add our force schedulers. Maybe the buildmaster tried to 
start the build right in between removing and re-adding the scheduler?

You could check your log for these lines before and after the exception (where 
'force' is your scheduler name):
2015-03-29 10:22:17+1300 [-] removing scheduler 'force'
2015-03-29 10:22:17+1300 [-] adding scheduler 'force'
