about

nx_vsz_watchdog.nx -- ONE-SHOT VSZ watchdog CLI (cron/piggyback-invoked): kills a conf-listed daemon whose VSZ crossed its threshold so the nx_hostctl guard respawns it FRESH -- automating the proven manual fix for outage MODE 2 (VSZ-bloat -> fork-fail -> child-exec silently empty; mgmt hit 160GB, restart -> 4.2GB and the exact failed /api/unpack succeeded). DEATH-DECIDER ONLY: respawn is the guard's (no dueling supervisors). usage: nx_vsz_watchdog [conf] [dry] conf default "vsz_watchdog.conf" rows: <cmdline-needle> <max_gb> FAIL-SAFE: no conf -> INERT exit 0; parse failure -> row dropped; unreadable status -> skip; cooldown 600s per row; never kills pid<=300 or itself. Always exits 0 (a watchdog must never fail the cron). license_tier: ORIGINAL expect_exit: 0
