👻 I know this an old thread....But, it appears that your statement, "Cable/DOCSIS Modem under load, and you've got a VPN on top of that", is spot on. I recently updated my Netgear DOCSIS 3.0 to a used/like new Motorola DOCSIS 3.1 from eBay for a few coins 😊 And thus far, I haven't received the frequent error messages, listed above in my first post, after ten days. It appears that this issues has been resolved, albeit it only has been 10 days with this new modem. I used to experience the error messages frequently almost daily and at least every couple days. My suspicion was always the cable modem since that particular Netgear cable modem uses the controversial Intel chipset instead of the Broadcom chipset, but the pfSense log confused the matter because it showed both the cable modem and my VPN were potential culprits. I pulled the trigger because the Motorola cable modem was such a good deal to pass up. Thanks for pointing out the cable modem was the most likely the culprit!👻
