Subject [jira] [Created] (AURORA-1808) Thermos executor should send SIGTERM to daemonized processes
Date Wed, 02 Nov 2016 20:06:58 GMT

------------------------------------

             Summary: Thermos executor should send SIGTERM to daemonized processes 
                 Key: AURORA-1808
                 URL: https://issues.apache.org/jira/browse/AURORA-1808
             Project: Aurora
          Issue Type: Bug
            Reporter: Zameer Manji
            Assignee: Zameer Manji


Thermos loses track of double forking processes, meaning on task teardown  the daemonized
process will not receive a signal to shut down cleanly.

This can be a serious issue if one is running two processes: 
1. nginx which demonizes and accepts HTTP requests.
2. A back and processes that receives traffic from nginx over a local socket. 

On task shutdown thermos will send SIGTERM to 2 and not 1, causing nginx to still accept traffic
even though the backend is dead. If thermos could also send SIGTERM to 1, the task would tear
down cleanly.
