If that's only options you use, there is another workaround: add options
rsize=1024,wsize=1024 to avoid possible packet reassemply/defragmentation
related bugs.

Again, error 4 is EINTR so you could disable both "soft" and "intr" options for test.
Anyway, re-read mount_nfs(8) manual page, section BUGS before switch to NFSv4.
