`Exception: API.bootstrap() already called` using `redhat.rhel_idm.ipaclient_setup_nss` with strategy mitogen_linear

[aarora2022]

I am using Mitogen 0.3.26 along with Anisble core 2.16.14 and python 3.11. While calling the Redhat IDM collection via playbook with mitogen installed in execution environment , its giving API already bootstrap error

My Execution enviroment ansible.cfg looks like below

[defaults]
interpreter_python = auto
strategy_plugins = /usr/local/lib/python3.11/site-packages/ansible_mitogen/plugins/strategy
callbacks_enabled = timer,profile_tasks
host_key_checking = False
 
[mitogen]
mitogen_via_localhost = false
 
[ssh_connection]
pipelining = True
ssh_args = -o ControlMaster=auto -o ControlPersist=2m -o ControlPath=/tmp/ansible-ssh-%h-%p-%r -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null

I have mentioned strategy=mitogen_linear in my playbook .

Ansible job error details are as below

Notes

• https://galaxy.ansible.com/ui/repo/published/redhat/rhel_idm returns a 404, so I infer redhat.rhel_idm collection is only for Red Hat paying customers.
• Red Hat usually develop upstream in open under a different name, then republished a QA'd version under their brand.
  • Red Hat IDM is built from FreeIPA
  • redhat.rhel_idm is probably from https://github.com/freeipa/ansible-freeipa

Ah, probably a repeat of #1216 (fixed in #1217). So has some bearing on #1255.

@aarora2022 please could you try your playbook task(s) that use this collection with this? It may workaround the problem

vars:
  mitogen_task_isolation: fork

Notes

• Description here lists ansible_collections/redhat/rhel_idm/plugins/modules/ipaclient_setup_nss.py
• I think that corresponds to https://github.com/freeipa/ansible-freeipa/blob/master/roles/ipaclient/library/ipaclient_setup_nss.py
• ansible_mitogen.planners.NewStylePlanner.ALWAYS_FORK_MODULES doesn't mention ipaclient_setup_nss

@moreati Thanks for your inputs. mitogen_task_isolation: fork resolved the issue
