My OPNsense has crashed a couple of times for no apparent reason. The system simply wasn't responding: no connected device was getting an IP address, although it was responding to pings. So I had to reset the system.
I've attached the log, but it's quite perplexing. The only thing I see is that the WAN DHCP6C interface stops responding (confirmed at 2026-01-15T01:41:07 by the Home Assistant log). I really don't see anything else that would indicate a problem.
Can a WAN interface failure cause the entire system to crash? I'm asking the experts to clarify this point because I don't know how to interpret it.
Thank you very much.
