Seems like an issue solved by PR #2565 (in current master branch, due to be part of NUT 2.8.3 release).

Are you in position to custom-build the current code base, e.g. following the https://github.com/networkupstools/nut/wiki/Building-NUT-for-in%E2%80%90place-upgrades-or-non%E2%80%90disruptive-tests page?
