For reference, this thread from Feb 2007 describes it at least once:
We saw this issue as well, but it apparently (for us), resulted in in
RIB sync slowness only; there was no (apparent, or at least major)
Somewhere around 8.x -- maybe 8.5 or earlier -- it got worse instead
of got fixed. Now it's causing significant packet loss as well.
Maybe we have a cornercase that got worse. Or there really are some
architecture specific differences that might explain the difference in
behaviour (in particular I'm speculating about VERY old, memory/CPU
constrained T320 FPCs). But the bad news is that JTAC's response is
that this is working as designed.
