Subject [jira] [Created] (MESOS-6938) Libprocess reinitialization is flaky, can segfault
Date Tue, 17 Jan 2017 23:17:26 GMT
Greg Mann created MESOS-6938:
--------------------------------

             Summary: Libprocess reinitialization is flaky, can segfault
                 Key: MESOS-6938
                 URL: https://issues.apache.org/jira/browse/MESOS-6938
             Project: Mesos
          Issue Type: Bug
          Components: libprocess, tests
         Environment: ASF CI, CentOS 7, libevent and SSL enabled
            Reporter: Greg Mann


This was observed on ASF CI. Based on the placement of the stacktrace, the segfault seems
to occur during libprocess reinitialization, when {{process::initialize}} is called:
