[tor-relays] mismatch between sent and received

Hello

There appears to be a growing mismatch between the amount of data sent and received for my relay. Most recent Heartbeats (in GB): sent received 8.07 10.87 7.30 10.10 6.87 9.68 6.41 9.22 6.18 8.50

This seems like something I should be concerned about, my are there GB of data that are stopping at my relay?

This is not an exit relay, it is running on a raspberry pi running raspbian (debian). Any thoughts? Thank you in advance,

Dave
