I have 2 full nodes (completely different networks) that I can watch side by side and one of them gets spurts of duplicate block challenges while the other doesn’t. Sometimes I’ll see 25 duplicates. The other one gets the odd duplicate, but not nearly as bad.
Does it happen to anyone else? Does anyone know what’s going on there?
My conversation was pretty brief, but was told that it would put extra load on the harvesters. So I think it’s mostly cosmetic unless you have a very underpowered harvester. I have no idea what would be considered underpowered (maybe a Pi?).
