I have a netgear R6220 with 19.07.5 that over the last few weeks has crashed a few times - it seems more so recently. It's a fairly standard build. It looks like I have about 33 dhcp leases. I have wireguard 'client' vpn and vpn policy routing and munin-lite installed beyond the basic packages.
Several times I haven't been able to access the web server or ssh in. One time I had an out of memory error. Yesterday I could but there was no wan connectivity. With ssh, reboot didn't work and I had to power down.
The munin reports, to me, don't show any obvious issues. It does seem that memory usage is increasing?
I did grab the output from top before rebooting yesterday (but after dns leases stopped being issued and wan connectivity had dropped.
Any ideas on what is causing this? Any information or log files I can grab if I notice performance degrading? Should I just reboot it memory use hits a certain threshold?
Thanks.
