David Capwell commented on CASSANDRA-17116:
-------------------------------------------
now that I don't try to hide channel close, it seems that python dtest is
failing as the logs show the exception. What is weird to me is that this
happens in the happy path as well, so not sure how things were "success" if the
session fails due to channel close...
> When zero-copy-streaming sees a channel close this triggers the disk failure
