[jira] [Created] (TS-936) Crashes do not generate core files due to setuid on Linux systems.

Crashes do not generate core files due to setuid on Linux systems.
------------------------------------------------------------------

                 Key: TS-936
                 URL: https://issues.apache.org/jira/browse/TS-936
             Project: Traffic Server
          Issue Type: Bug
          Components: Core
    Affects Versions: 3.1.0
         Environment: Linux
            Reporter: Alan M. Carroll
            Assignee: Alan M. Carroll
             Fix For: 3.1.1


Each process on Linux has a flag indicating whether a core file should be created from a crash. This flag is reset by setuid() and equivalent system calls. The core logic attempts to deal with this but is incorrect and therefore no core file is produced regardless of host operating system settings.
