Unexpected error on add manual throttles

When I try add manual throttle, I get an error:

ERROR: Too many tag throttles have been created (2111)

It can be reproduced like this:

docker run -d --rm --name fdb foundationdb/foundationdb:7.3.43
docker exec -ti fdb fdbcli 
configure new ssd single
throttle on tag rest

On version 7.1.X everything is OK.

Could you try with 7.3.27 ? Be aware that pre-release have high chances to contain bugs (7.3.43 is a pre-release)

Checked version 7.3.27, the behavior is the same.
