Why BrokenPipe error?

[dungeontiger]

We have seen this error in the past but now it is becoming more frequent. Do you have any idea what could cause this?

{ kind: BrokenPipe, error: "ZipWriter was already closed" }

This is from our cargo file:

zip = { version = "0.6", features = ["deflate","bzip2","deflate-miniz","deflate-zlib"] }

It's a mystery to me why this would happen, especially since it seems random and infrequent. Any clues would be really helpful.

Does this error go away when you replace zip with zip_next?

Do you have a code pattern example ? 

Do you always write/flush after calling start_file (or a variant) ?
