Dear genfiters,

when testing genfit on dch hits I noticed that memory consumption grows steadily with the number of analysed events. In a fast check on stt data I observed the same behaviour, that's why I think it might be a problem in genfit itself (memory leak?). Can anyone have a look?

cheers,
ola

Hi Ola,
Actually i have the same problem as you have now.
I solved( at the moment works) by doing the following

In the directory of genfit
if you go to the class Track.cxx
at the line 26
add the line
delete trackReps

Track::~Track() {
22 if(trackReps!=NULL){
23 for(int i=0;i<getNumReps();i++) {
24 delete trackReps->At(i);
25 }
26 delete trackReps; }
27 for(unsigned int i=0;i<hits.size();i++) {
28 delete hits[i];
29 }
30 }

if you have a task to extract the information
from the track object,
PNDDchKalmanQATask for example

at line 150 add also fTrackarray->Delete();

i hope it works

best regrads
Alicia S.
