Where is it leaking from? If it's from the top, I would think it's compromised bladder seals/mating surfaces. If it's from the bottom, through the shaft hole, it's probably bad o rings or scratched shock shafts.
Mostly, these shocks leak through the bottom(unless you have a messed up mating surface at the top of the shock or beat threads at the top of the body/cap.
As a first measure, polish the shafts with Mothers metal polish, and replace the o rings. I've always had to use lots of green goo to prevent leaks, but I service my shocks about every 6-8 weeks of use (1 practice day and 1 race day=about 8-10 runs/week) and usually catch any issues before it's actually a mess.
Edit to add: The bottom seal keeper insert may be coming loose in dynamic use, too. Sounds mostly like a bad shaft, though, which is why I say polish it and try again.
