Description

While trying to get logs for #30992, my client started emitting those:

[warn] Middle node did not accept our padding request.

The context is that a normal client (git master) is trying to reach a service that is under _heavy_ load as in quite unreachable.

I've managed to catch info logs of this from the bootstrap of the client up to the warning.

I am tentatively labeling this 041-must?, but we can downgrade it if it turns out not to be a serious bug.

Mike, could you please have a look at this?

Mike took a look at this during PETS and I don't think he considers it a serious bug. The warning has also been downgraded to protocol warn in 041 as part of #30649.

I leave the ticket open so that Mike can summarize what he found out in case it's a bug that needs to be fixed, but I'm removing it from the 041 milestone.
