Can you specify the branch(master/stable-Be) and the condition - did you have any switches connected? I assume its a single node test and not a clustered one and you used "shutdown -f" to shut it down gracefully, am i correct ?

Hello Colin,

Can you check if this issue still exist.
if the issue exist, then can you provide logs and scenario/use case.

I was running Beryllium-SR1 and was connecting a small number of OVS instances using mininet, then running a ping from one host to another followed by shutting things down and saw this. My guess is that you can close this as wontfix because it's from Beryllium and I don't have a good way to reproduce it.

Closing as per Colin's comments.
