Subject [jira] [Commented] (MESOS-1705) SubprocessTest.Status sometimes flakes out
Date Fri, 15 Aug 2014 20:05:18 GMT

    [ https://issues.apache.org/jira/browse/MESOS-1705?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14099021#comment-14099021
] 

Benjamin Mahler commented on MESOS-1705:
----------------------------------------

This would be because we recently turned on google-logging stacktraces in the libprocess tests.
Note that the test is still passing but the child process seems to have received the SIGTERM
after the fork but before the exec, which is fine but produces this unfortunate stack trace.

[~vinodkone] perhaps we should drop the SIGTERM stacktracing, like we do within the mesos
logging initialization.
