Hey Olof, Thanks for the screenshot. I believe something like this has been observed before, but I'll need some time to find it, maybe it's unrelated. My intuition right now is that it's related to how the Firebase library opens/holds/fails to close threads. Could you provide as much detail as possible about the system you've set up, versions of any libraries, details about the runtime environment, etc.?
Thanks for your patience in the meantime, I hope to have more to report tomorrow.
