2 years ago I think this one is explainable. For some reason the mempool had >10,000 transactions around that time (March 5). So most likely the (average) fee of those transactions was not high enough to be mined within an hour and then this happens.
ALT-743 improved this error, maybe this has not been released yet.
Franmf was testing with 3 miners each with a different wallet. the case is that he noticed that they started to show this error, and he's not even able to confirm the block. They are sharing same nodecore, could this be related ?
