My guess here is either the test isn't disposing of something it should be disposing of in order to close files, or the implementation itself is keeping something open when it shouldn't.

[ViktorHofer]

Should we disable the test meanwhile or first wait what Jeremy says?

[stephentoub]

I suspect if it's an issue with this test it's also an issue with other tests. It'd be good to understand the problem and then either disable everything that might be affected or just fix it. If we're unable to do that today-ish, we could just disable this one.

[ViktorHofer]

Sounds good

This is the same 😂

I hadn't refreshed the page to see you already commented :)

Moving to future, a long disabled test without clear customer impact
