ModuleNotFoundError: 'mmap' is present in the Mitogen importer blacklist

[ondrejkopka]

• Ansible 2.15.8

• Ansible is not patched

• No custom modules

• Did not tried latest master version from Git?

• Debian 12 (Bookworm)

• Host Python 3.9.2, target Python 3.11.2

this task:

- name: wait for port 53 to be open on localhost
  wait_for:
    host: localhost
    port: 53
    state: started
    timeout: 120

leads to this error:

An exception occurred during task execution. To see the full traceback, use -vvv. The error was: ModuleNotFoundError: 'mmap' is present in the Mitogen importer blacklist, therefore this context will not attempt to request it from the master, as the request will always be refused.

Sorry for the wait. I wasn't able to to reproduce this error, with the following

- hosts: localhost
  vars:
    ansible_python_interpreter: /usr/bin/python3.11
  tasks:
    - wait_for:
        host: localhost
        port: 22
        state: started
        timeout: 5
