When in cluster mode, MOVED replies (which are arguably not even errors) are aggregated per slot-id + remote host, and displayed in # Errorstats as such. For example, in a server that does not own 8k slots, we will aggregate 8k different errors, and their counts (in memory).
This slows down all INFO replies, takes a lot of memory, and also makes INFO replies very long.
The fix:
Use typeMOVED for moved replies, making them all the same under # Errorstats
