Traffic intermittently stops flowing following upgrade to 22.1

[jsmg]

I upgraded from 21.7 to 22.1.2 last night, and ever since then I have been having an issue where I suddenly lose internet connectivity, requiring a reboot to fix. The WebUI remains responsive, I don't see anything that stands out as suspicious in the logs (the one in the WebGUI, anyway), and the only clue I have is that when I SSH into the router when it's in this state and try to ping an external address I get the following error:

Code Select Expand

Enter a host name or IP address: 8.8.8.8

ping: sendto: No buffer space available
ping: sendto: No buffer space available
ping: sendto: No buffer space available

Does anyone have suggestions on how to troubleshoot this? It's incredibly disruptive since my wife and I both WFH full-time.

Could it be the same issue that me and a few others are having over here?

I that issue with two itens:

Too much strict QOS rules.
My suricata gave the white smoke when i overloaded it with too many rules for the server i was on.

Thanks for the replies. This doesn't sound like the same issue as either of you, I'm not using Wireguard (in fact, I removed the plugin) and I don't really use any QoS rules. I use this at home and have a very basic setup, it was mostly port forwarding, local DNS, and DuckDNS updating. I don't know if I'm using Suricata, I may have just absentmindedly turned it on when I first set everything up but I've never actively configured it.

Late last night, it started failing consistently within 5 minutes of a reboot. My wife was about to murder me so I was forced to disconnect it and setup my Eeros instead. (Previously they were just in bridge mode.) I'm going to have to find a way to play around with it as a secondary device behind that router since there are just very few times where it's okay for the Internet to be down around here.

Ugh. Thanks again for the help, guys.
