Hey Guys,

I'm a long time FreeNas user and I've had 10G Nic's in my servers for years. I started having problems in 11.0 with the change of the jails virtualization system. Whenever a jail is started when running on 10G the server becomes unresponsive until I kill all jails from the command line.

I've tested this on every version hoping that they'll some day fix it but I finally decided to post. I'm running 11.1u5 and I've got the intel X520-da2 10G cards.

Has anyone else seen this behavior?

I am not seeing this with my system, but I am only using one jail and it is an old warden plugin for FreeNAS that I have been using for years.
It might be something about your jails configuration. Can you give more details?
Do you have any other networking configured besides the 10G card?

I've read over in another Freenas Forum that it has something to do with the network bridging for the jails. The 10G driver or hardware doesn't like it. What they've done is some how bound the jails bridging to a 1G copper interface and everything else runs off of the 10G just fine.

Only problem I see is I don't know how to bind the jails bridging interface to the 1G

You are going to need to give details on your hardware and what jails you are running in addition to how they are setup. Are they warden, io cage, something else? Someone on this forum will be happy to help you find the problem and either fix it, or advise you to submit a ticket to the bug tracker.
Either way, you must communicate, in greater detail, what the situation is.

I use 10Gig networking with my FreeNAS and I have seen no problems at all with my jail. That leads me to the conclusion there is some configuration issue with what you have configured, which is why we need to explore your configuration.

No, that is not the correct way to fix the problem. It might make it work, but it isn't the right way to do it.

If you only want this answer, you might start with looking at this thread:

Create a bridge in FreeNAS.
https://forums.freenas.org/index.php?threads/bridge-between-network-interfaces.41566/#post-270035

You can look at the reference on how to modify the bridging in BSD here:
https://www.freebsd.org/doc/handbook/network-bridging.html

Just keep in mind, you will have to create and run a post-init script to make the changes after the FreeNAS configuration finishes loading.
