Description of Issue/Question

Setup

I have salt-master 2018.3.3 which was working under Ubuntu 16.04 and Python2 for a long time. After upgrade to Ubuntu 18.04 and Python3 error messages started to appear.

Steps to Reproduce Issue

key_cache: 'sched'

Results in:

2018-12-13 07:53:11,853 [salt.utils.process:754 ][ERROR   ][5051] An un-handled exception from the multiprocessing process 'Maintenance-94' was caught:
