makefile quickly results in No space left on device

This has been my experience over the past few months (?) just manually zipping and side-loading, slower and slower until inevitably "no space on device" error, need to do "system restart".

yep. exactly the same here - in my case it was worse because I didn't have the correct excludes so the zip was bigger and had zip files in it.

I'm also noticing that it does it way more (almost every time), if sideloading while the app is in a breakpoint, especially on another thread
trying to remember to q out the console before I start off another build 🙂

I hadn't been experiencing this while developing on an Ultra but today I'm working on a Roku 3 and running into this issue.

I got the same issue using sublime text exporter. Developing on Roku Express... had to restart the system but I would like to try using makefile to deploy. 

BTW, I've adopted the habit of first deleting the existing channel, then sideloading the new version, and I haven't had the issue ever again. It's possible the issue was fixed via firmware and my actions are only coincidental, but it made sense to me that it would help.
