intr and soft are considered dangerous with nfsv4. See the "BUGS"
section of the mount_nfs(8) man page.
Currently I am see dangerous w/o intr: system need reboot, application

NFSv4 confiders "intr,soft" dangerous for data generated by poorly written

Just switch back to NFSv3 if you value reliability of your machines more.
NFSv3 processes "intr,soft" just fine.
