Hmmm... try cssutil -r <cssfile>  and post the results here.

It may be the case that you do indeed have too much stuff in there and
the relay chains are just getting too long.

Ahhh- "aging" - the Castle Anthrax of text recognition.

That is a problem, which is *not* circumvented by any system I know of.

All of those wonderful examples of spam from five years ago are
completely obsolete, and possibly misleading.

My advice is (sadly) that you can't really "age" it - the easiest 
thing to do (which will at least give you more space and make too-long
chains shorter again) is to use cssmerge to create a bigger file
(disks are bigger now, dude!)

Other than that, you can start again.

Some (a few) versions of cssutil also had the ability to 
zeroize small bin values.  That might be useful at least for
speedup- however, accuracy will suffer as you are lobotomizing
out low-count samples.

Make a copy of your .css files before you do that!

Failing that, you're in for a retrain.  :-(
