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
