From 856735da395d2af34831af5546ae0dea127f30a1 Mon Sep 17 00:00:00 2001 From: Daniel Gaspar Date: Thu, 30 Apr 2026 13:27:04 +0100 Subject: [PATCH 1/3] fix(alerts): reset stuck WORKING reports to NOOP instead of ERROR on timeout MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When a Celery worker crashes (OOM, pod eviction) mid-execution, the report stays stuck in WORKING state. Previously, after working_timeout elapsed, it transitioned to ERROR — which for daily schedules meant no retry until the next day (24-hour wait). Now it transitions to NOOP instead, so the next scheduled cron tick picks it up and retries naturally. This avoids duplicate execution risk (no immediate retry that could clash with celery broker requeue) while ensuring daily schedules recover promptly.

Previously, after working_timeout elapsed, it transitioned to ERROR — which for daily schedules meant the report wouldn't actually retry until two days later (day 1: crash, day 2: timeout fires → ERROR, day 3: cron sees ERROR → retries). Now on working_timeout it resets to NOOP and immediately re-executes via ReportNotTriggeredErrorState in the same tick. This is safe because by the time working_timeout (typically >= 1 hour) has elapsed, any celery broker requeue (~30 min) has already been attempted and rejected with ReportSchedulePreviousWorkingError — so there is no duplicate execution risk.
