[jira] [Created] (AURORA-1808) Thermos executor should send SIGTERM
to daemonized processes
Zameer Manji created AURORA-1808:
------------------------------------
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.
