I am NOT reporting a (potential) security vulnerability. (These should be emailed to security@ansible.com instead.)

Bug Summary

Seeing "Job terminated due to error" in the UI on a very simple playbook (below).

In the UI it looks like this:

In the logs around the end of this job I see this:

awx-task 2023-05-27 14:52:07,144 INFO     [2d7014133ee34ad9b12564981b1764b2] awx.main.commands.run_callback_receiver Starting EOF event processing for Job 93

In the UI job output it looks like this (note that this should count to 8000):

Here's the playbook:

---
- name: long_log_lines
  hosts: localhost
  connection: local
  gather_facts: false
  vars:
    how_many: 8000
    delay_secs: 1

  tasks:
    - name: Create a list
      ansible.builtin.command:
        cmd: seq {{ how_many }}
      register: the_list

    - name: Set a fact for the list
      ansible.builtin.set_fact:
        the_list: "{{ the_list.stdout_lines }}"

    - name: Ping list times
      ansible.builtin.shell:
        cmd: |
          echo {{ item }}
          sleep {{ delay_secs }}
      loop: "{{ the_list }}"

AWX version

22.3.0

Select the relevant components

Installation method

kubernetes

Modifications

no

Ansible version

Whatever the AWX 22.3.0 EE is running

Operating system

Kubernetes 1.24.4

Web browser

Chrome

Steps to reproduce

Running this very simple playbook; it should be easy to reproduce.

Expected results

That the playbook completes without error.

Actual results

The playbook ends with "Job terminated due to error".

Additional information

I'd urge that this is triaged pretty highly, it'd be impossible justifying running this in production. The reason that I'm running such a trivial playbook is that we have some in production (non-trivial) that run for quite a long amount of time.

I've reproduced this many times now:

fosterseth · 2023-05-31T17:33:41Z

what k8s cluster are using? (eks, kind, k3s, etc)

what is your awx spec file?

how many job events get produced before the job errors out? Is it consistent for each job failure?

mamercad · 2023-06-01T01:41:15Z

what k8s cluster are using? (eks, kind, k3s, etc)

k3s 1.24.4

what is your awx spec file?

It's stock 22.3.0; I don't really know what you mean by "awx spec file", could you elaborate?

how many job events get produced before the job errors out? Is it consistent for each job failure?

Seems like it generally dies at around 4300 lines.

Could you try reproducing it in your environment?

Here's the playbook if you just want to clone it.

Same simple playbook, set it to count to 6k and it only got to about 4300 before "Error: Job terminated due to error".

TheRealHaoLiu · 2023-06-06T20:42:01Z

can you check the kubelet container-log-max-size configuration for your k3s cluster?

one possibility is due to log size and cause log rotation in kube which you will need to enable RECEPTOR_KUBE_SUPPORT_RECONNECT described in

ansible/receptor#683

TheRealHaoLiu · 2023-06-06T20:50:26Z

back of napkin calculation each run of Ping list times produce about 2000Bytes of data in stdout
8000 run of it produce about 17.25 MiB of data

by default kubelet container-log-max-size is 10MiB according to https://kubernetes.io/docs/reference/command-line-tools-reference/kubelet/

unless k3s configures the kubelet differently and overrides container-log-max-size this playbook seems like it WOULD run into the log rotation and would require RECEPTOR_KUBE_SUPPORT_RECONNECT

mamercad · 2023-06-07T12:11:52Z

can you check the kubelet container-log-max-size configuration for your k3s cluster?

I think it's 10Mi by default with k3s, I'm testing with k3s server --kubelet-arg container-log-max-files=4 --kubelet-arg container-log-max-size=50Mi currently and will report back.

I'll try RECEPTOR_KUBE_SUPPORT_RECONNECT as well.

mamercad · 2023-06-07T13:17:08Z

Good news, the job completed with the updated kubelet log arguments:

For the next test, I'm going to try 9000 lines and I'm going to add RECEPTOR_KUBE_SUPPORT_RECONNECT.

TheRealHaoLiu · 2023-06-07T14:18:25Z

can you please update the name for the issue to reflect the actual problem

"Task was destoryed but it is pending" seem to be coming from the asyncio library which is used in the wsrelay component (websocket) unlikely its related

mamercad · 2023-06-07T16:53:57Z

I need to bump k3s to try the Receptor argument: https://github.com/ansible/receptor/pull/683/files#diff-792611baeb730234abface9c9bc33204ea86453469e7fcdfbe8de8d4e04f2598R659

I can do that, and, I'll report back when I've done that and tested.

mamercad · 2023-06-07T17:59:51Z

I can do that, and, I'll report back when I've done that and tested.

k3s bumped to 1.24.14, Receptor flag set, trying with 16k lines ...

mamercad · 2023-06-08T07:19:03Z

I think this issue is resolved, 16k lines is complete (both in the UI and the downloaded logfile).

❯ wc -l ~/Downloads/job_36.txt
   16022 /Users/mmercado/Downloads/job_36.txt

The job took nearly 6h which makes me feel good as well.

To summarize, I bumped k3s to 1.24.14 (for the Receptor argument) and am now running k3s server --kubelet-arg container-log-max-files=4 --kubelet-arg container-log-max-size=50Mi.

Lastly, I added:

        ee_extra_env: |
          - name: RECEPTOR_KUBE_SUPPORT_RECONNECT
            value: enabled

to the AWX spec.

Klaas- · 2023-06-22T15:22:36Z

if I run with RECEPTOR_KUBE_SUPPORT_RECONNECT enabled, it does reconnect, but it seems to "lose" content.

So for the reproducer by @mamercad I see in the log of a running job:

changed: [localhost] => (item=13111)
changed: [localhost] => (item=13112)
changed: [localhost] => (item=19886)
changed: [localhost] => (item=19887)

maybe related #14158

Klaas- · 2023-06-22T15:27:49Z

Details of the two executions:

  "cmd": "echo 13112\nsleep 1\n",
  "start": "2023-06-22 10:55:45.976451",
  "end": "2023-06-22 10:55:46.983008",

  "cmd": "echo 19886\nsleep 1\n",

  "end": "2023-06-22 13:22:36.649521",

~140 minutes between those two where the logs have not made it into AWX
