I've also managed to track down the cause of this problem.
Although the internal linkUp/Down monitoring did indeed
have the '-S' flag set, to suppress the startup tests, this
wasn't working correctly.
   It did suppress traps from the initial monitoring pass (as intended),
but unfortunately, the *second* monitoring pass would then trigger
a linkUp trap for any link that was up, and a linkDown trap
for any link that was down.
  (And the links that were only half way up, were neither up nor down).

I've also applied a patch that fixes this problem as well.
Again, that will be included in the upcoming 5.4.2 release.
