It doesn't give you an exact solution, but it does hint at what you've taken the time to point out above. I've set "maxpoll 9" on each "server" entry, on each of our boxes. So far (48+ hours later), still no signs of FLL/PLL switching. Very cool. Thank you very much for this recommendation. :-) -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
