What we see is that the scraper container have finished (containers f506be0a1d31 and 32424149f271 gone).

But the task containers which are responsible to manage the whole task execution are still there (containers ad7dfd16fe54 and 4aed9b3cd658).

@kevinmcmurtrie could you please give us the last lines of these two containers as well?

They don't seem to be doing anything.

So clearly it looks like we have a concern on the task manager which is not detecting that scraper container has finished / stopped (or not checking anymore maybe ...)

Thank you @kevinmcmurtrie ; next time please include the inspect output (at least the State part).

Task manager queries docker API for scraper container status and condiders the following as running:

zimfarm/workers/app/common/docker.py

Line 39 in dc4a00f

RUNNING_STATUSES = ("created", "running", "restarting", "paused", "removing")

  • We can exclude created and running and restarting from what was shared. It's possible the containers were paused (external cause, zimfarm doesnt pause containers) or removing (something preventing removal from finishing) though.

I'd wait for another occurrence (with the status clue) before taking action
