[danhole]

pfSense 2.3.4-RELEASE-p1 (i386 nanobsd)
seems to have started a few weeks after upgrading to this version, before it was very stable
reboots at least once a day i have attached the console output which shows the bt

can anyone offer me some guidance on what the issue may be

Hi,

99 % sure its a hardware failure, FreeBSD freaks out during its idle loop and knowing that this loop is by far the most executed code on every device, I consider it without bugs  ;)
The only thing you can do : check out the RAM and storage of your device.

edit : if possible - and if present, change the power block and use an UPS.
