Ooh, lock contention on the hardware CAM table or the software in the switch that handles these updates? The first time I am hearing about this bug :-) Thanks

Thanks a lot for sharing this bug story!
- imbriaco 14y agoIt was a lock that was being held by software but also prevented hardware updates to certain hash locations in the CAM. So MAC addresses that hashed to those locations couldn't be learned by any means.
- brooksbp 14y agoI wonder what hash was in use. Also, what workaround were you using to prevent flooding while this issue was happening?
