Mubsub: broken cursor

See original GitHub issue

I have 2 apps both using feathers-sync, both on the same servers and both connecting the same mongo replica set although using seperate databases. But on one of the app I keep getting this error.

I’m posting in here as feathers-sync is the only package I have installed that uses mubsub which hasn’t been updated in a while and doesn’t look like any of the issues are being answered.

Looking at other issues like #110 and #119 it looks like Mubsub just doesn’t work very well with newer versions and does not appear to be maintained anymore. I’m inclined to remove it.

I was planning on completely replacing mubsub with a from-scratch implementation of a MongoDB collection watcher but didn’t get to it yet.
