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
