Do you observe the same behaviour when you pull a cable?
Maybe a flapping port might cause this kind of behaviour, other than
that you should't see any network disconnects.
Are you sure about LACP configuration, what is the output

Are you sure about LACP configuration, what is the output of 'cat

Which hash mode are you using on the hosts? layer 3+4 ? Are they set up
active/active, or active/passive?
I often see suboptimal bonding configurations that result in most or all
traffic going over only one ilnk.
