Problem with latest 1.9 zwave

I am using the latest master branch. On start all my devices start to work, but after a few hours things start to drop off the network and continue to do so until only my zwave stick and repeaters are green. Any ideas? The solution for me has been to restart every few hours, but I would like to try to avoid that.

Other than database updates there have been no changes to 1.9 for several months so unfortunately I’ve got no ideas - sorry. I’d suspect it’s not a binding issue, but maybe something else.
