From 74da641b129bfb9ab9ee4d0e19dc2208aa5651ce Mon Sep 17 00:00:00 2001 From: JamBalaya56562 Date: Sun, 19 Apr 2026 09:35:02 +0900 Subject: [PATCH] fix: reap HEALTHCHECK zombies by running tini as PID 1 Node.js as PID 1 does not reap children it did not spawn, so the HEALTHCHECK curl fired every 10s accumulates as .
