Thanks for the tip. I had downloaded a prerelease source version of NUT 2.8.1, built and installed it. Evidently there was an issue with upssched consuming 100% CPU. I downloaded the current release and the issue has been resolved. Updating all 3 systems.

Am i the only user who has no glue about how to build a new version for my system? I?m running on Raspberry GNU/Linux (bullseye) v 11, which might be similar to your system? Sounds as if it is not a big issue to download the version and build it and install it. Is there anybody out there who might be able to give me a kickoff, how to do that? Have found various built versions here at Binary packages - Debian packages https://packages.debian.org/search?keywords=nut but using 2.8.0.7 did install the newer nut, but nut-client and nut-server were again 2.7.4. using nut-client and nut-server standalone and of newer versions did refuse to install Von: Nut-upsuser <nut-upsuser-bounces+edward.ebay=t-online.de at alioth-lists.debian.net> Im Auftrag von Dan Grostick via Nut-upsuser Gesendet: Mittwoch, 6.

Updating all 3 systems.Is possible, please fill bugreport against Debian nut package. Would be nice if the developer could fix this in debian-provided version.>On Tue, Mar 05, 2024 at 08:37:32AM +0000, Dan Grostick via Nut-upsuser wrote: >> My Raspberry PI 3B was overheating - 70 degrees C.
