Task enabled, schedule fine. Check scheduler state + last run logs.
Luci
Scheduler is systemd service kicked every min by cron. Check service status + log around the gap.
Luci
Last run 07:01:10 (late), 08:00 missed. Check if scheduler ran at all at 08:00 — did OTHER tasks fire?
Luci
Big gap: no task fired 07:01→08:51. Scheduler stalled ~1h50m, then flood at 08:51. data-freshness-check still not in catch-up batch. Check cron + scheduler lock/log.
Luci
flock `-n` global lock = smoking gun. One tick spawned long-running crypto morning brief, held `/tmp/scheduler.lock` ~1h50m. Every minute's tick `flock -n` failed → ALL tasks stalled. Confirm from log.
Luci
Need timestamps. Find what tick was doing during 07:01→08:51 gap.
Luci
No timestamps in log; DB is source of truth. Established: **all** tasks stalled 07:01→08:51, not just this one. Current scheduler PID holds `flock -n /tmp/scheduler.lock` running a long synchronous crypto morning brief. Root cause = a long sync task mid-tick blocks the rest of the tick AND holds the global lock so next minute's `flock -n` ticks all no-op. Let me see how the tick runs tasks (sync vs background) and which task is the offender.
Luci
crypto-brief sched 07:30, timeout 600 — not the 07:01 trigger. Find which task actually held the lock 07:01→08:51 (long/unfinished run).
Luci
Root cause CONFIRMED. **investment-weekly-digest** ran synchronously 07:01:15→08:51:02 = 6587s (1h49m), holding global `flock -n /tmp/scheduler.lock`. Every minute tick failed lock → all tasks stalled → 08:00 slot missed. And it's recurring live now: crypto-trader-cycle (08:54:07, still running) is blocking again, data-freshness-check ('d', next alphabetically) not yet reached.
Bug = long sync task inside tick holds global lock > cron interval. Let me see how scheduler decides sync vs background.
Luci
Architecture clear: tasks run **synchronously** in the tick unless `background: true`. investment-weekly-digest (claude task, NotebookLM 45min waits) isn't background → blocked everything for 1h49m. crypto-trader-cycle is doing it live now. Fix = mark the genuinely-long tasks `background: true`. Check the offenders' defs.
Luci
investment-weekly-digest: timeout **7200 (2h)**, sync — the culprit. crypto-trader-cycle (300s) and crypto-trader-brief (600s) also sync, blocking hourly/daily. All should be `background: true`. Let me verify the background path handles `run_as: shell` and still enforces timeout (so a hung NotebookLM job stays bounded).
Luci
Background reconcile records exit but doesn't kill a hung background PID. Need to confirm there's a stale-lock/timeout killer for background PIDs so a hung NotebookLM job stays bounded.
Luci
reap skips live background PIDs — so background tasks never block other tasks (tick returns fast, no global lock held). Moving the long tasks to `background: true` fully fixes the cross-task stall. Quick audit: which other non-background tasks have large timeouts that could re-trigger this?
