> Tracking an issue raised by Chronos users that appears to be a regression in Mesos: https://github.com/mesos/chronos/issues/381#issuecomment-83647539
> 1) Chronos's interval between refusing offers and receiving the next one is at 0.1 seconds
to allow finer grained scheduling of jobs.
> 2) On single node clusters running Mesos 0.20.1 with both Chronos and Marathon installed,
Marathon did not receive any offers. On multi-node clusters, this behaviour was not observed.
This behaviour was not observed when using previous versions of Mesos.
> 3) Changing this interval back to the default value (i.e., by not setting it) fixed this
problem. (See [commit|https://github.com/mesos/chronos/commit/fb1ab1c42207b12c8663457d07c322fc81a8ec2e].)
> This can be replicated using an installation of playa-mesos and running both the latest
Mesosphere packages of Chronos and Marathon.
