 Hi everyone,

 I have a program which fills in many histograms (55 histograms being
 TH1F or TH2F) without doing special calculations or being complex.

 I don't anderstand why if I fill only 47 histograms it takes 50s to run
 and if I fill 48 it takes 300s... And it doesnt care about which
 histograme are in the 40 or in the 41...
 Is there any special memory allowance that would explain this fenomenon
Is it something about using TH2 ?
