[ROOT] histogram->write() problem

Dear Rooters, 

I have a problem with th1f->Write(). If you look at the sample code bellow, what I do is I fill a histogram then I want to save it and redefine it it with different x-axis, refill it, save it etc. So the code bellow is executed again and again. When the ->Write() statement is commented out, the code works ok. When I introduce the write statement the code crashes after a random number of iterations. 

This code bit is part of a lrager multithreaded application, and it could be that it's an indirect problem with my code. However maybe it's simple and direct, that's why I would like your advice.

Thanks

Dimitris


TH2F *hEquiMap[2];
.....
//******************** loop ************************
 if (tim>eqStop[1])
 {  
      if (hEquiMap[1]) { 
               TreeOutFile->cd(); 
              hEquiMap[1]->Write(hEquiMap[1]->GetName(), TObject::kOverwrite); 
               hEquiMap[1]->Delete();
         }
 
          eqStart[1]=eqStop[0]-equi_width2;
          eqStop[1]=eqStart[1]+4*equi_width2;
          eqBins[1]=(eqStop[1]-eqStart[1])/2+1;
          ceqname2.Format("equim_%i",eqStart[1]);

          hEquiMap[1] = new TH2F((LPCTSTR) ceqname2,"Equiphase Map",eqBins[1],eqStart[1],eqStop[1],POptionspdaTotalPixels/4,1.,float(POptions->pdaTotalPixels));

          hEquiMap[1]->SetFillColor(1);
          hEquiMap[1]->SetContour(128);


 }
