Running Ansible 2.4.2.0 on OSX 10.13.2 (via macports), python version 3.6.4.
I'm running a playbook of some 100-odd tasks and this error occurs at some
point in that operation. I can repeatedly run the playbook and get
successively closer to the end.
Some operations must run; if everything is skipped then no error occurs.
The stack trace usually seems to point to a handler, but I can't spot the
error.
With "-vvv":
the full traceback was:

It would seem that the error is happening when notifications are collected,
e.g. one task after which the failure occurs. Note that this is one task
in the middle of several which do the "notify":
- name: install hiredis 0.13 shared library
> become: yes
> copy: src={{ item.src }} dest={{ item.dest }} mode={{ item.mode }}
> with_items:
> - { src: "libhiredis.so.0.13", dest: "/usr/lib64/", mode: '0755' }
> tags: provision, hiredis, redis_fdw
> notify:
> - name: restart postgres
The handler definition:
---
> - name: restart postgres
> become: yes
> service: name="{{ pg_service }}" state=restarted
> - name: reload sysctl configuration
> become: yes
> shell: sysctl -p /etc/sysctl.conf
