Question about FSHammer getting full

[Sdävtaker]

Hi, I got  a hammer FS running 59 days (today was 60, recopy is scheduled every 30, maybe a coincidence, maybe not)The thing is the Hd got full today, i destroyed some old PFSs to make some space (6GBS) and 5 minutes after it was full again, im guessing something is filling it real fast, but dont know where to look at :-/
It does mirror copy  from other mahcines every 30 minutes, but stopped that before remove the 6GB.Any ideas, suggestions?If i found it, and i stop it, is there a way to remove the full story from all snapshots of those specific files consuming all?
Thanks for any ideas.Damian
