Checking the logrotate script is does a 'service foreman-proxy condrestart'.
I think that the startup might be too quickly after the stopping so the port 9090 is not released yet for re-use.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Force logrotate logrotate -f /etc/logrotate.conf
Foreman-proxy is not listening the port 9090
Foreman-proxy is listening again on the port 9090

Apparently the issue is still there. I don't think adding a delay between launching http and https apps is a great approach (slows down startup, 5 seconds may not be sufficient time to for the process to release the socket). Updating 'sigterm' handler to stop http and https apps and then exit smart-proxy would be my preferred approach.

- Subject changed from Capsule stops listening on 9090 after log rotate to Smart proxy stops listening on HTTPS port after log rotate
- Category set to Core
- Priority changed from High to Normal
Or provide another signal handler just for rolling logs, avoiding the need to restart at all.
