From 3fadf89e432c1a3ee8b2f8a036fe477a1715d305 Mon Sep 17 00:00:00 2001 From: Molecule AI Infra-SRE Date: Thu, 14 May 2026 17:27:31 +0000 Subject: [PATCH 1/6] fix(ci): kill stale platform-server before binding port MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Cancelling or timing out a workflow run leaves the platform-server process alive — the "Stop platform" step (line 335) is skipped. If the stale process is still on an ephemeral port, the next run's socket.bind(("", 0)) can receive a port still in TIME_WAIT, or the stale process may interfere with the /health probe. Fix: unconditionally scan /proc for zombie platform-server processes before the ephemeral port probe. Only kills processes whose cmdline contains "platform-server" (safe — ignores other Go binaries). Uses only shell builtins + grep + kill — available on any Ubuntu runner. The /proc comm field is truncated to 15 chars, so the binary named "platform-server" appears as "platform-serve" in /proc/*/comm. cmdline is verified before kill to avoid false positives.
