We think today's nightly build has addressed the memory issues we’ve been seeing. While there were certainly a few memory leaks fixed along the way, and we now also support zram swap, the final bug looks to have been a change in the vm.min_free_kbytes setting. This was being set to 16M per core, so it could easily reserve half of available memory for the system “just in case” use (making it unavailable for use by applications). We’ve dropped this back down to 1M per core, and have seen many hours of stability in places we were lucky to get an hour from.
This nightly build is pretty much a "must have" if you're running supernode tunnels on an ac2, and "highly-recommended" if you're running tunnels on a hAP ac Lite
Again, test with caution, but we're comfortable that the memory issues are behind us.
