Hi,

Although the problem is solved, I think it worth documenting it! the Finish() method in CbmTask is called at the end of the task and not for each event, in the PndMicroWriter task, the TClonesArray->Delete() is called in Finish(), which led to the memory leak because the Tracks where never deleted!

Hi Mohammad,
thanks again for your help.
So now what are your advices?
Should i call anyway the Finish()
method at the end of the Exec in every task?

I know that for the Track objects is specially
dangerous, not to delete the TObjectArray at the end of the event.

Therefore i#m using the call ofFinish() at the end of the exec
for every Task where i read a track object.

best regards
and i owe you a cake Surprised

Alicia.

Hi try to add
fTrackArray->Delete()
at the of the Exec method
of the PndMicroWriter.Task

and at /genfit directory
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 }

compile everything again
and try to run thr runReco.C.

I hope it works
best regards
alicia.
