             Summary: Port not re-offered after task dies
                 Key: MESOS-3764
                 URL: https://issues.apache.org/jira/browse/MESOS-3764
             Project: Mesos
          Issue Type: Bug
          Components: scheduler driver
    Affects Versions: 0.23.0
            Reporter: Serhey Novachenko


I have a Mesos framework configured to accept a specific port for tasks (31150 
in my case) and I have amount of tasks == amount of slaves so basically I have 
a task running on each slave on port 31150.

I have Mesos slaves configured to offer 4000..7000,31000..32000 and I was 
successfully running all tasks until one of them threw an exception and died. 
The framework got the TASK_FAILED status update and I expected the task to be 
relaunched on the same machine and port but instead my framework says no offer 
has port 31150 in it. Is there a case when Mesos does not re-offer the port of 
dead task?
