I just had this happen so I am making a post in case it happens to anyone else.
I have a fully updated TrueNAS Core 13.0-U2 that has been happily serving SMB shares to an active directory environment for 21 days. Today I had planned to move my unifi controller to a jail running on this server. I went to the community plugins and chose unifi server, chose dhcp as the network option. It got to 50% progress and then…
The web interface went down, the server fans suddenly hit 100% and my network registered a broadcast storm so heavy that my entire network choked. I had to hard power off the truenas machine to get even the dhcp server to come back to life.
I have no idea if it was me that overlooked something or what? I will note that the server is an HP DL380 Gen 10 with 4 gigabit nics and a 10G Card I installed myself. I’m afraid to turn it back on now and will probably try again during off hours but does anyone have any idea why that would have happened?
