I have a really weird problem for which I have no explanation. Last week I changed the ethernet switch that a freenas box was using from a 100mbps switch to a gigabit switch, thus allowing the gigabit port on the freenas box to use its gigabit capability. Nothing else was changed, and nothing was changed on the freenas server at all.
Since then, web interface on the freenas server keeps dying. I can restart the server, and the console menu says the web ui is availalable on the correct address and port, and the web UI works immediately after boot. Sometime after that, withing 10 minutes or so, the web interface stops responding, and if you hit return on the console to reload the menu it pauses for a long time before reloading and then sends a message saying it's unable to access the web interface. Ssh access to the box also fails.
The box continues to serve nfs fine, though. It does its job, you just can't pull up the interface.
More puzzling still, we have a duplicate machine that acts as a backup server. It's the same in every way, and I also moved it to the new switch, and it is not having this problem.
Both systems are running 11.1-U6.
