Jobst,
We recommend to compile the Cint generated files in noopt mode. In
particular
under AIX, you gain a huge amount of compilation time.
For the "memory leak" problem, do you get the same problem if you run only a
few events,
if yes, could you send me the ouput of TTree::Print immedialy before
file->Write().
Could you also check that when you create the Tree, you indeed have a TFile
object
as the current directory? Otherwise root will try to create this Tree in
memory
and it may take a lot of memory to save it as one single object to a file.
