I think there may be more to it than just mwan3 in a fail-over config and wireguard. I have a x86_64 running 18.06 with mwan3 (2 wan interfaces in a load balance/fail-over setup) and wireguard with 2 configured clients and have not had any issues. I can post my exact setup if requested; I just don not have access to it at this minute.

I seem to be having a similar issue, although this is on the latest stable 19.07 branch and using build 19.07.7, but I have experienced the described issue on older releases i.e. 19.07.3

I too am also using mwan3 with multiple internet connections and VLANs. My CPU stalls also reference Wireguard in the kernel logs, however interestingly it is when I disable my L2TP interface things return to normal, rather than disabling Wireguard itself, but I wonder if it due to mangle/fwmark. I have experienced several issues with L2TP and fwmark in other use cases too.

I can replicate this because after a restart of my router (Linksys WRT3200ACM) approx 3 hours of 45 minutes of up time, the router stops responding and starts to encounter CPU stalls, the system load climbs up and then the router starts to go completely unresponsive, then returns to normal and then repeats this in a loop. During the time when the router is briefly working, I can see that some of the network interfaces uptime have reset, the only thing that seems to stop the CPU stalls is disabling my L2TP interface for a while and then starting it again, which then everything is fine. If my router is rebooted i.e. sysupgrade, this cycle will happen again around 3 hours and 45 minutes of uptime. It is very strange, but this issue seems to possibly what is happening to me as well.

I seem to be experiencing a very similar issue on 19.07.7 so I request this is reopened for further analysis. I have also experienced CPU stalls with Wireguard on older versions like 19.07.3 as well. The common factor here appears to be a combination of mangle/fwmark, VLANs and mwan3. I have reason to believe my issue may be related to L2TP, or PPP based network interfaces.

As this has been migrated to GitHub, I'd like to update it that this still occurs on OpenWrt 21.02 and given it's been originally reported in 18.06, I suspect there's a edge case somewhere but it's not as obvious because it requires a combination of factors which are typically not present for many.

The combination for me is either mwan3, fwmark, VLANs, wireguard/L2TP but like clockwork after around 3 hours and 45 minutes of uptime. My router (Linksys WRT3200ACM) will start to encounter CPU stalls and in some cases just reboot itself because it's experienced a kernel panic.

If I don't enable my L2TP connection for a while after starting up, it can avoid triggering the above behaviour and then work fine for months.

The CPU stalls indicate wireguard related processes though, typically wg-crypt.
