"An alternate cause of EIO on networked filesystems is when an advisory lock had been taken out on the file descriptor and this lock has been lost."

"When an advisory lock is obtained on a networked filesystem such as NFS it is possible that the lock might get lost. This may happen due to administrative action on the server, or due to a network partition (i.e., loss of network connectivity with the server) which lasts long enough for the server to assume that the client is no longer functioning.

When the filesystem determines that a lock has been lost, future read(2) or write(2) requests may fail with the error EIO. This error will persist until the lock is removed or the file descriptor is closed. Since Linux 3.12, this happens at least for NFSv4 (including all minor versions)."

write_size is the return value from writev / write.
5 is EIO Input/output error

Maybe you're just supposed to retry in those situations?
