LEAKED DESCRIPTORS OVER THE SAME WINDOW: 388 (all ESTABLISHED on :8007)

  requests by libwww-perl + proxmox-backup-client :  162404   descriptors leaked: 0
  requests by Go-http-client/1.1 (felhom-agent)   :     811   descriptors leaked: 388

  Go-http-client GET .../snapshots calls          :     387
  leaked ESTAB sockets                            :     388   -> ratio 1.0026 (ONE per call, within 1)

  Per box, at the instant of reading A:
    ep0 ESTAB from 10.77.0.2 (demo-felhom) = 194 ; from 10.77.0.3 (demo-hp) = 194
    demo-felhom ESTAB to 10.77.0.1:8007    = 194 ; demo-hp                  = 194
    194 + 194 = 388 = ep0 total.  Both sides agree EXACTLY -> Q2 outcome (a).

CADENCE RECONCILIATION (why 194 and not 185):
  hub report poll  poll_seconds=900   -> 184.7 cycles in the window
  pbs VerifyLoop   DefaultVerifyCadence=6h -> 7.7 cycles in the window
  sum                                  -> 192.4   observed leaked/box: 194
  observed POST .../verify per box in the window: 8  (matches 7.7)
  observed GET /version per box: ~185.5 (matches the 184.7 hub cycles)

  Mean interval between leaked descriptors, per box:
    857 s = 14.28 min   (900 s poll + a 6 h verify cycle superposed)
