There's likely something wrong in your network.  Here's an output from
one of our machines.  This is the machine on my network with the nearest
"sent pack" I could find to yours -- though it has a couple more rounds
:-)

============================
Status at www-va-3 V 3.17. 1 (state 1, gstate 1) after 5522361 seconds :
Membership  :  5  procs in 1 segments, leader is admin-va-1
rounds   : 1568978308   tok_hurry : 12989386    memb change:      20
sent pack: 6085701      recv pack : 13342698    retrans    :      42
u retrans:      42      s retrans :       0     b retrans  :       0
My_aru   : 4564420      Aru       : 4564420     Highest seq: 4564420
Sessions :      49      Groups    :      45     Window     :      60
Deliver M: 18192098     Deliver Pk: 19495195    Pers Window:      15
Delta Mes:     712      Delta Pack:       0     Delta sec  :     157
