Description

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?
