Ram fills to point where app pauses when freezing Rotobrush?

[JordanLloyd]

When attempting to freeze a rotobrush pass, my system ram fills to 100% and causes OSX to "pause" After Effects thus stopping it from running. I have 96GB of ram, and this is the latest AE build, running on 10.12.

Shouldn't AE purge itself or something along the way to prevent this from happening? Currently I can only really keep it going by manually purging the limited amount of ram held in cache via 'sugo Purge' in a Terminal window.

This particular clip is 4K which is probably testing the limit of the software, but I definitely don't think it should behave this way?

Has anyone run into this and found another workaround, other than the obvious known common rotobrush workarounds?

1. If you haven't already, try transcoding your footage to a lossless format, then replace with the previous probably heavily compressed footage. The try to freeze.

2. Try the secret menu and disable layer cache
