||
# PURPOSE
|
||
# ─────────────────────────────────────────────────────────────────────────────
|
||
# Pressure reduction layer — detects rising system load and reduces it before
|
||
# things break. Called by watchdog_orchestrator.sh every minute as a single-
|
||
# pass run. The middle layer between docker_watchdog.sh (fixes broken
|
||
# containers) and system_watchdog.sh (reboots). Does neither of those things.
|
||
#
|
||
# ==============================================================================================
|
||
# OPERATIONAL MODEL
|
||
# ==============================================================================================
|
||
#
|
||
# Three-Level Pressure Response
|
||
#
|
||
# Level 1 — SOFT (RAM < RW_RAM_SOFT_GB OR load > RW_LOAD_SOFT_MULTIPLIER × cores):
|
||
# Throttle SABnzbd download speed to RW_SABNZBD_SPEED_SOFT.
|
||
# Throttle qBittorrent download to RW_QBIT_DL_SOFT KB/s.
|
||
#
|
||
# Level 2 — MEDIUM (RAM < RW_RAM_MEDIUM_GB OR load > RW_LOAD_MEDIUM_MULTIPLIER × cores):
|
||
# Further throttle SABnzbd + qBittorrent to medium limits.
|
||
# docker pause RW_PAUSE_CONTAINERS — suspend without losing state, instantly reversible.
|
||
#
|
||
# Level 3 — HARD (RAM < RW_RAM_HARD_GB):
|
||
# docker stop RW_STOP_CONTAINERS — optional/heavy services (games, LocalAI, etc.).
|
||
# Write mem_shutdown_active=true → signals docker_watchdog to defer container restarts.
|
||
#
|
||
# Recovery
|
||
# Pressure must stay below current threshold for RW_RECOVER_CYCLES consecutive
|
||
# runs before restoring. De-escalates one level at a time — prevents re-triggering
|
||
# immediately after recovery. Level 3 additionally requires RAM >= RW_RAM_RECOVER_GB
|
||
# before containers are un-stopped.
|
||
#
|
||
# Coordination with docker_watchdog.sh
|
||
# At level 3, writes mem_shutdown_active=true to RW_STATE_FILE.
|
||
# docker_watchdog.sh reads this and defers all container restart logic.
|
||
# Without this, docker_watchdog would immediately restart containers that were
|
||
# just stopped to free RAM — defeating the purpose of level 3.
|
||
# Cleared when pressure resolves and containers are restarted.

||
