<![CDATA[High CPU and temperature hit when key expires?]]>Hi,

the other day I noticed that my appliance (i7 CPU) was running extremely hot (70°C) and the CPU was at 70% (usually it's at 15-16%). I checked the temp stats and it turned out that it was in sync with an expired TS authentication. Even stopping and re-starting TS on pfsense didn't fix it. After generating a new pre-auth key on the TS site and filing the key into TS on pfsense all went back to normal (15% CPU) and the machine cooled down significantly (back to the usual 40°C CPU).
Maybe this is a known issue but it seems like TS on pfsense (v2.6.0) goes into some weird state that taxes the CPU extremely when a TS key expires?

My appliance as hot as a frying pan when I came in this morning and Tailscale was hung. Logs show the temp went up at 3AM to almost 100°C. 3AM is usually the time when my ISP does a short dis/reconnect. Any idea how to fix this other than disabling Tailscale?
