Not sure where to post this. This morning I came into work and it was reported to me that the internet was not working. I did notice my laptop was not connecting to the wifi, so I assumed it was an issue with the access points or their controller. So I disabled wifi and plugged my laptop into ethernet. Still, no connection, either on the local LAN or the WAN. I could not even navigate to the IPFire web interface. So I went to the firewall, connected directly via keyboard/mouse, and issued the reboot command. It rebooted cleanly and when it came back up, internet and local LAN was working. I then logged into the web interface and scanned a bunch of graphs and waded through the logs and saw nothing of note. The gateway graph did not show any drops. The only thing remotely suspicious was a small spike in cpu just prior to me rebooting:
My next thought was it ran out of memory, but I still had plenty free prior to the reboot:
The bandwidth usage was pretty much non-existent between 4:00am and 6:30am. There was a person here as early as 5:45am and they reported the internet was not working from the time they came in until I rebooted IPFire. I’ve added the red rectangle around this time period in the screenshot below:
My only other thought was maybe the LAN NIC got locked up. Any other ideas? It’s working fine since I rebooted 4 hours ago. Just curious if I could find a root cause or not.
Thanks.
