I had a similar issue about 2 months ago. I was using XDG_LOG_HOME in a 
shepherd service definition, and it was not available anymore.
The error message I got was different, but the result was the same - some 
services shown as "starting" and working, but herd <command> not working for 
one particular broken service.

I suggest to check your 
/gnu/store/zbfyaxxigns5lqyxhxzxhm92w54ns1cz-shepherd.conf file for the log path 
of the mcron job. Maybe your XDG_STATE_HOME points to a non-writable directory?
