i dont exactly know how to ask for help on this... nor have a reproducible minimal example...
I downgraded back to 1.15.1 from 1.16.2 and have the same issue there.
I have a pipeline that's repeatedly failing to complete. it correctly marks things as cached, and then just doesnt execute the last step. The task stays "Running" forever, but disappears - the worker just has a process that dies. CPU/RAM aren't running out or anything like that at all. Prior runs of this pipeline worked just fine (less cached then too).

Has anyone seen this kind of "disappearing / zombie task" state before? It's very perplexing to me.

hoping this really is a 1.16.2 issue. fingers crossed. at this point more pipes are failing than not.

None here's how I'm establishing worker-server (and client-server) comms fwiw

when i run the pipe locally, im using the same connect.sh script as the workers are in order to poll the apiserver via the ssh tunnel.

enqueuing. pipe.start("default") but I think it's picking up on my local clearml install instead of what I told it to use.

my tasks have this in them... what's the equivalent for pipeline controllers?

I think i've narrowed this down to the ssh connection approach.

regarding the container that runs the pipeline:

  • when I made it stop using autossh tunnels and instead put it on the same machine as the clearml server + used docker network host mode, suddenly the problematic pipeline started completing.
    it's just so odd that the pipeline controller task is the only one with an issue. the modeling / data-creation tasks really all seem to complete consistently just fine.

so yeah, best guess now is that its unrelated to clearml verison but rather to the connectivity of the pipeline controller task to the api server.

when I run this pipeline controller locally (also using the same ssh tunnel approach for comms), the pipeline completes just fine. so it's something specific about how its working inside the container vs on my machine, it seems.

do you have any STATUS REASON under the INFO section of the controller task?

I will ask internally about this

Hi @<1689446563463565312:profile|SmallTurkey79> , when this happens, do you see anything in the API server logs? How is the agent running, on top of K8s or bare metal? Docker mode or venv?

but maybe here's a clue. after hanging like that for a while... it seems like the agent restarts (the container it runs in does not)

thank you

do you have the agent logs that is supposed to run your pipeline? Maybe there is a clue there. I would also suggest to try enqueuing the pipeline to some other queue, maybe even run the agent on your on machine if you do not already and see what happens
