Hi,
I am now convinced that RooAddPdf::fitTo leaks memory.
In my analysis I need to do multiple independent fits (in different bins of observable space) So I have few hundred fits.
I need to run pseudoexperiments to check performance and debug the machinery.
I call the fit in a standard way like this:
RooFitResult* r_extravar=0;
r_extravar=sum_extravar[i_extravar][i_bin]
->fitTo((data_binned_extravar[i_extravar][i_bin]),
Extended(),Minos(kTRUE), PrintLevel(-1));//,Save()) ;
where
data_binned_extravar[i_extravar][i_bin] is a RooDataHist
sum_extravar[i_extravar][i_bin] is RooAddPdf*
Now if I just comment out the second line (and leave everything the same - pseudodata preparation storing results etc) the memory consumption is stable. If I do run the fit as desired memory blows up by ~20MB/pseudoexperiment which is not sustainable…
I am using root 5.27.04
please help…
Thanks,
Wojtek
