Hardware and Performance / Devices periodically start disconnecting, then all fail. Hard reboot resolves.
« on: May 03, 2023, 09:43:38 pm »
I have a relatively new OPNsense install that I recently integrated to replace an Asus router. The system is up and running great, except for a really baffling issue.
At seemingly random times every 2 days or so, I'll notice a device goes offline (usually an IoT device where I will get an offline notification through the management app). Other devices will slowly also start having connectivity issues until all of a sudden nothing is on the network after about 15-30 minutes from the start of the symptoms. It's like nothing is getting an IP address and the DHCP service has just failed entirely. I am seeing a bunch of entries like this in the DHCP service log:
Error dhcpd lease 192.168.55.14: no subnet.
Not exactly sure what is causing the issue, but as soon as I do a hard reboot of the machine running OPNsense, everything works normally again as soon as all services start up. The problem seems to be global as it doesn't matter what subnet or VLAN a device uses, they all eventually fall victim to the cascade failure.
DHCPD Log HERE for reference. Let me know if any other logs or config info would be helpful for diagnosis.
