All the offers that were sent between 05:59:07 and 06:16:26 were counted as
outstanding_offers by Mesos master. This gap in time keeps on increasing from
minutes to hours until I restart the Scheduler process. How can I find out
where these outstanding offers are queued up for minutes before being offered
to Scheduler and why is there a delay of minutes?

> Key: MESOS-10143
> URL: https://issues.apache.org/jira/browse/MESOS-10143
> Project: Mesos
> Issue Type: Bug
> Components: master, scheduler driver
>Affects Versions: 1.7.0
> Environment: Mesos Version 1.7.0
> JDK 8.0
>Reporter: Puneet Kumar
>Priority: Minor
>
> We manage an Apache Mesos cluster version 1.7.0. We have written a framework
> in Java that schedules tasks to Mesos master at a rate of 300 TPS. Everything
> works fine for almost 24 hours but then outstanding offers accumulate &
> saturate within 15 minutes. Outstanding offers aren't reclaimed by Mesos
> master. We observe "RescindOffer" messages in verbose (GLOG v=3) framework
> logs but outstanding offers don't reduce. New resources aren't offered to
> framework when outstanding offers saturate. We have to restart the scheduler
> to reset outstanding offers to zero.
> Any suggestions to debug this issue are welcome.
