#3610: Buildbot does not realize latent worker has disconnected
Reporter:  skelly     |      Owner:
    Type:  undecided  |     Status:  new
Priority:  critical   |  Milestone:  undecided
 Version:  master     |   Keywords:
 When using build_wait_timeout=0 and a worker is disconnected once the
 build finishes, Buildbot does not realize the worker has disconnected.
 This probably happens when build_wait_timeout is a value other than zero
 too, but it needs to be checked.

 2016-09-14 20:26:08+0000 [-]  <Build BUILD>: build finished
 2016-09-14 20:26:09+0000 [-] OpenStackLatentWorker runner-8 terminating
 instance 778261e4-4875-408d-a26e-744ad49f500e (runner-8)
 2016-09-14 20:26:09+0000 [-] releaseLocks(<OpenStackLatentWorker
 u'runner-8'>): []

 The log disconnected the worker but the UI still shows the worker as
 connected. If another build is started on the worker, nothing happens.
 Buildbot doesn't fix this until it tries to ping the worker and then the
 ping fails and the worker can be instantiated again.
