Although this item has not yet caused abends, I am assuming this is the
proper forum in which to bring this issue to your attention and to seek

We have a 13-server environment (all NW6.5 Sp5) with locations across the
US. Six servers are at our headquarters in Massachusetts; the others in
each of our satellite offices
Lately we are experiencing a virtually constant level of NCP traffic
between all "pairs" of our servers to the tune of at least 150Mb even
during the overnight hours when virtually "nothing" is happening other
than backups in each office.
Our tree is quite static and replica placement is, I believe, adequate and
not overdone. What should we be looking at?
Thank you in advance for any assistance.
