Meng Zhu commented on MESOS-9014:
---------------------------------

After discussing with [~greggomann], looks like the segfault happens due to a 
race during the test tear-down.
The test looks for a particular task status update. A segfault would happen 
when the scheduler receives another task status update and tries to acknowledge 
the update, and in between, the scheduler got tear-down.

A possible fix is to kill the task and wait for the task kill status update 
explicitly before test tear-down.
