[{"type":"thinking","thinking":"Two PIDs: 19740 (parent) and 37300 (child). Per memory: \"detached spawns show as parent+child pairs (normal)\". But wait — watchdog.py isn't a server that forks; why a child? Memory says detached spawns show as parent+child pairs, normal. The log shows only ONE \"watchdog started\" entry at 21:39:55, so only one watchdog main() is running. The parent (19740) is the spawned launcher... actually Popen directly launches watchdog.py, so 19740 should be the watchdog itself. The child 37300 — hmm, maybe the detached process re-launches? Only one log line, so only one instance executing main(). This matches the documented \"parent+child pairs (normal)\" pattern. Good — exactly one watchdog running.","signature":""},{"type":"text","text":"Done. Exactly **one watchdog** is now running (PID 19740; PID 37300 is its child — the normal detached-spawn parent+child pair, and the log confirms a single `watchdog started` entry at 21:39:55 UTC).\n\nSituation found: all three earlier watchdog instances had died hours ago (last log entry 18:57 UTC, no matching processes) — only the Django server was still up.
