From ddf480e6edc7eef819392d6cc3e0ffe5e0fc9269 Mon Sep 17 00:00:00 2001 From: CyberMind-FR Date: Tue, 17 Mar 2026 07:39:09 +0100 Subject: [PATCH] fix(droplet,dpi): Resolve publish hang and broken pipe errors - dropletctl: Remove pipe to grep that blocked on background children - metablogizerctl: Background HAProxy generate/reload (~90s with 95 certs) - dpi-lan-collector: Pre-compute flow counts in single pass instead of spawning grep per client (eliminates broken pipe errors) Publish time reduced from ~2 min to ~35 seconds.
