I installed a NSv 300 into production yesterday and saw something strange. I used the PMTU Discovery tool and the appliance web UI hung completely. Command line and the ESXi console still worked, but I had to reboot the appliance to get the web UI back.
Anyone else seen something like this? I've sometimes observed with physical appliances that the web UI can become unresponsive but it often resolves by itself after a moment. I mean unresponsive where the page doesn't load at all in the browser.
