opnsense-revert -r 26.1.7 nut
pkg lock nut


this fixed my issue as well. THANKS!!! Interesting when trying to figure out why my NUT status was no longer working, Claude informed me that a UI bug has been around since 2021. Not sure if that's related or what but thanks for this temp fix anyway.

I am very new to opnsense.
Environment
OPNsense 26.1.4 (amd64)
Hardware: HP Pavilion tower, AMD A12-9800 CPU
NICs: igc0 (WAN), igc1 (LAN), re0 (DMZ)

Problem
samplicate is running at 100% CPU continuously. It was configured with two NetFlow destinations (127.0.0.1:2055 and 127.0.0.1:2056) but nothing is actually consuming data on those ports — sockstat confirms nothing is listening on 2056 and only samplicate itself is on 2055.

Reproduction steps
Any attempt to stop samplicate causes an instant silent reboot loop that requires restoring a config backup to recover. Attempts made:
— GUI: Clearing NetFlow destinations and hitting Apply
— CLI: service netflow stop
— CLI: kill <pid>
— CLI: ngctl shutdown ksocket_netflow_igc0: then ngctl shutdown netflow_igc0: then kill <pid>
All result in an immediate reboot loop. System log captures nothing before the reboot — the kernel appears to die before it can write to disk.

Diagnostics
— /var/crash/ is empty — no crash dumps generated
— dmesg shows no panic or fatal entries
— monit is not watching samplicate (monit summary shows only System and RootFs)
— samplicate is launched via daemon wrapper by /usr/local/etc/rc.d/netflow
— netflow stop uses kill -9 on samplicate then ngctl shutdown on netflow nodes
— UPS is healthy (CyberPower 1350VA, 100% charge, OL status)
— No os-netflow, os-insight, or os-ntopng plugins installed — NetFlow is OPNsense core

Current netflow.conf

netflow_interfaces="igc0"
netflow_egress_only="igc0"
netflow_version="9"
netflow_int_destination="127.0.0.1:2055"
netflow_destinations=" 127.0.0.1/2055  127.0.0.1/2056 "
netflow_active_timeout=1800
netflow_inactive_timeout=15
Question
Is this a known issue with netgraph + samplicate on this kernel version? Is there a safe way to disable NetFlow/samplicate without triggering a kernel panic? Is there a way to enable crash dumps to capture the panic for a proper bug report?

Any help appreciated. Happy to run additional diagnostics.
