This is gonna be one of those times where everyone on the list has a
different opinion. Here's mine: I'd go forward rather than backward. If you
have trouble with 6.1.3 you can drop back to the 6.0.x branch. If you still
have trouble, then go back to earlier releases.

In my years using Ascend stuff, the trend has been that things have gotten
_much_ better over time. That's a trend, not an absolute.

I run 6.1.3 fta.m40 with an uptime of 11 days and no crashes, etc.
whatsoever since loading 6.1.3.

I have an unusual config on that 4000, though: NO switched connections and
a single Frame T1. AppleTalk routing. Would like OSPF. :-(

With a config like that, I'd _better_ be a poster child of 4000 reliability
under 6.1.x. ;-)

One caveat: if you go to 6.x you may have trouble with LQM, so be prepared
to turn it off if you have troubles. A bug was introduced somewhere in 6.0
and I'm not sure that it's fixed yet. It certainly isn't fixed on the TNT
in 2.1.3.
