             Summary: Libprocess reinit code leaks SSL server socket FD
                 Key: MESOS-6919
             Project: Mesos
          Issue Type: Bug
          Components: libprocess
            Reporter: Greg Mann

After [this commit|], it was 
discovered that tests which use {{process::reinitialize}} to switch between SSL 
and non-SSL modes will leak the file descriptor associated with the server 
socket {{__s__}}. This can be reproduced by running the following trivial test 
in repetition:
diff --git a/src/tests/scheduler_tests.cpp b/src/tests/scheduler_tests.cpp
index 1ff423f..d5fd575 100644
