I wish it was a single issue, at least then I would have one definite
thing to bitch about. It's more like a dozen different issues affecting
the same subsystem, in a dozen different versions of code, over the last
couple of years. You could say the same thing about SNMP, it's been
broken about as many times over about as many different revisions
(including recent ones :/).
10.4S9 does seem to have solved this latest issue, which was causing
wildly inaccurate reservations. It's almost comical when RSVP tries to
reserve a several petabit LSP (not much to do with recent JUNOS except
laugh at this point, right? :P), but it's a lot less funny when nearly
empty high-priority LSPs get mis-calculated to several gigabits and
start causing incorrect preemptions...
