Running this command: dd if=/dev/zero of=./data.raw bs=1M count=1024 Results in EIO on write() or close() on some systems. It's been seen with the 4.4.0 and 4.5.0 client, and on at least RHEL 6 and Fedora 23. So far it's only been seen with the Windows client. The cause is currently unknown. We have not seen any errors over the wire, so it might be a locally generated error because the Linux kernel gets upset over something unfsd sends. OTOH it's difficult to analyse this much data as wireshark's dissector gets confused and refuses to decode most of it.
