Hello all 11.x users. I would like to inquiry if your seeing this message set in your /var/log/messages file happening at random times during the day? kernel: Interface: watchdog timeout kernel: Interface: link state changed to down kernel: Interface: link state changed to up The Interface being the one connected to your ISP. I am getting this interface hardware hand shake error messages a few times an hour to a few times a day. Totally random. The server can be at total idle and it still happens. The watchdog timeout is a interface hardware hand shake error and the interface down/up is how the watchdog recovers from this error. I have gotten this error message group running 11.0 and 11.1 on a amd64 system and on i386 system, gigabit interfaces em0 and vge0, and 10/100 interface rl0 and xl0. Also with 2 different modems, a gigabit modem and a 10/100 modem. The gigabit modem has an admin system with an event log and there has never been a event logged of any kind. When this watchdog error happens and I am watching a streamed movie on my windows10 pc attached to the LAN the connection is lost to the streaming server and I have to login in again and start at beginning of movie. But the real problem is what this watchdog reset does to any aliases attached to that interface. Before the reset the first inet on the interface is the ISP issued IP address followed by what ever number of aliases I may have added. After the watchdog reset the first inet is now the first alias and the ISP IP is the last inet in the list. This causes the internet connection to vanish. I have to reboot or manually remove all the aliases so the ISP IP address inet is the only thing remaining on the interface and then the internet connection is restored at which time I have to re-add all the aliases again. This alias re-order problem is a strong indicator that this a kernel software problem. This post is just am attempt to see how wide spread this is. So please take the time to review your logs as you may be unaware this is happening to you. Thank you
