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.

that's the final screenshot. it just shows a bunch of normal "launching ..." steps, and then stops all the sudden.

clearml-server-1.15.1, clearml-1.16.2

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?

did you take a look at my connect.sh script? I dont think it's a problem since only the controller task is the problem.

Is there some sort of culling procedure that kills tasks by any chance? the lack of logs makes me think it's something like that.

I can also try different agent versions.

trying to run the experiment that kept failing right now, watching logs (they go by fast)... will try to spot anything anamolous

damn, it just happened again... "queued" steps in the viz are actually complete. the pipeline task disappeared again without completion, logs mid-stream.

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.

odd bc I thought I was controlling this... maybe I'm wrong and the env is mis-set.

can you share the logs of the controller?

thank you

would it be on the pipeline task itself then, since that's what's disappearing?
I will do some experiment comparisons and see if there are package diffs. thanks for the tip.

default queue is served with (containerized + custom entrypoint) venv workers (agent services just wasn't working great for me, gave up)
