I'm using version 4.1.1+git20181002-062a328 (self-compiled).? The log is
at https://www.dropbox.com/s/secyu9lddtqlt4t/motion.log
This is the 4th camera I've added to this setup, the other three work
fine with MJPEG.

I'd suggest you to set up a test environment and use single motion-dist
config to test only one camera at a time. Because usually, if browsers are
able to read mjpeg stream, motion should aslo be fine
