Subject [jira] [Created] (MESOS-7102) Crash when sending a SIGUSR1 signal to the agent.
Date Fri, 10 Feb 2017 00:36:41 GMT
Anand Mazumdar created MESOS-7102:
-------------------------------------

             Summary: Crash when sending a SIGUSR1 signal to the agent.
                 Key: MESOS-7102
                 URL: https://issues.apache.org/jira/browse/MESOS-7102
             Project: Mesos
          Issue Type: Bug
          Components: agent
    Affects Versions: 1.2.0
         Environment: ubuntu 16.04
            Reporter: Anand Mazumdar
            Priority: Critical


Looks like sending a {{SIGUSR1}} to the agent crashes it. This is a regression and used to
work fine in the 1.1 release.

Steps to reproduce:
- Start the agent.
- Send it a {{SIGUSR1}} signal.

The agent should crash with a stack trace similar to this:
