Hey, I seem to be seeing the same error popping up from the metadata-service-v2 ERRORAsyncPostgresDBglobal:Exception occurred. I can't see any resource constraints on the metadata services nor our postgres instance in RDS. We're running a t3.small at the moment, what I did notice was the ReadIOPS were hitting limits so I upgraded from GP2 -> GP3 storage and also created indexes to help irradiate some of the huge scans I was seeing and this has helped lower the IOPS read significantly. I see a few others have mentioned this issue previously but thought best to ask as each use case is sometimes different. I restarted the service about a week ago also so we'll be on the latest metadata service also.

do you see that error in the service log ? if so can you post the full log, maybe there are some clues
