"eos_snmp_server" gets stuck with no errors

[ivanchakarov]

SUMMARY

The "eos_snmp_server" collection is not working at all - when I run a task (the parameters doesn't matter) it always get stuck with no error messages and never completes.

ISSUE TYPE

• Bug Report

COMPONENT NAME

arista.eos.eos_snmp_server

ANSIBLE VERSION

ansible [core 2.15.8]
  config file = /home/ichakarov/arista-switches/ansible.cfg
  configured module search path = ['/home/ichakarov/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python3/dist-packages/ansible
  ansible collection location = /home/ichakarov/.ansible/collections:/usr/share/ansible/collections
  executable location = /usr/bin/ansible
  python version = 3.10.12 (main, Nov 20 2023, 15:14:05) [GCC 11.4.0] (/usr/bin/python3)
  jinja version = 3.0.3
  libyaml = True

COLLECTION VERSION

# /home/ichakarov/.ansible/collections/ansible_collections
Collection Version
---------- -------
arista.eos 9.0.0  

CONFIGURATION

CONFIG_FILE() = /home/ichakarov/arista-switches/ansible.cfg

OS / ENVIRONMENT

Arista vEOS-lab
Software image version: 4.31.1F

STEPS TO REPRODUCE

Run a play including the collection "eos_snmp_server" - the provided parameters don't matter. This is most probably the easiest scenario - gather the device's SNMP config:

- name: SNMP test
  arista.eos.eos_snmp_server:
    config:
    state: gathered

EXPECTED RESULTS

The main expected result is the task completion.

ACTUAL RESULTS

Unfortunately, in never finishes and gets stuck at "redirecting (type: connection) ansible.builtin.network_cli to ansible.netcommon.network_cli"

I observe the same behavior if I provide configuration parameters as well (state: merged, for example).

TASK [snmp : SNMP test] ***********************************************************************************************************************************************************************************************
task path: /home/ichakarov/arista-switches/roles/snmp/tasks/main.yaml:1

@ivanchakarov can you provide persistent logs ?

[bmhughes]

I'm seeing the same behaviour, the python process just pegs a CPU at 100% and never completes or outputs anything.

[marcvanhoutum]

The same behaviour is displayed with Ansible 2.17.9 and module versions 9.0.0 and 10.1.1.
