# Phase 5 additions vs original:
|
|
# - Restart=on-failure: systemd restarts Gunicorn if the master exits non-zero
|
|
# - Gunicorn --timeout: workers that don't respond within 25 s are replaced
|
|
# - Gunicorn --graceful-timeout: allows in-flight requests to finish on reload
|
|
# - PrivateTmp, NoNewPrivileges, ProtectSystem: basic systemd sandboxing
|
|
# - StartLimitIntervalSec / StartLimitBurst: caps restart storm

# NO WatchdogSec here — deliberately.
|
|
#
|
|
# WatchdogSec requires the service to send WATCHDOG=1 keepalives over the sd_notify
|
|
# socket. Gunicorn only does that when systemd exports NOTIFY_SOCKET, which happens
|
|
# only under Type=notify (+ NotifyAccess=main). This unit is Type=simple (the
|
|
# default), so no keepalive was ever sent, systemd treated the service as hung, and
|
|
# SIGKILLed it every ~30 s. Restart=on-failure then brought it back after RestartSec,
|
|
# producing a repeating window of 502s from Nginx.
|
|
#
|
|
# Hung *workers* are already handled by Gunicorn's own --timeout above; a crashed
|
|
# *master* is already handled by Restart=on-failure below. The watchdog added no
|
|
# coverage, only outages.
|
|
#
|
|
# To re-enable it properly (optional), all three lines are required:
|
|
# Type=notify
|

# NotifyAccess=main

# WatchdogSec=30s
