Sorry for the delay. I was a bit off this week.

Can you give me some more info on the issue? All tests pass so I can't reproduce your error.

I tested with an empty test module (with only use ExUnit.Case) to see if that would generate it but it generates properly. So, if you can show me some way to reproduce it I can see about a fix.

[KronicDeth]

Unfortunately this is triggering in a closed source project. I might be able to submit a use case once we open source some of the libraries. Feel free to close this and I'll comment once I have a use case.

I'll leave this one open. If people pass through the same thing they can collaborate here.

Do you think it might have anything to do with #8 ?

[KronicDeth]

Unclear if it is related to #8. IIRC it happened most often when there were enough crashes to bring down parts of the app's supervision trees as I remember seeing SASL logs too appearing.

[cs-victor-nascimento]

Hey @KronicDeth! I've released version 1.1.0 which covers umbrella apps. Maybe this issue was related to that. I was just curious if you are still having these issues.
