Hi,

I have a very simple code that write a root file through RFIO.

For small files it works fine, with big ones, the resulting root file is corrupted. Any suggestion? Thanks.

 $ /libcern/root/5.32.01/sl5.7-x86_64/bin/root AGATREE-rfio.root

• W E L C O M E to R O O T *

ROOT 5.32/01 (tags/v5-32-01_at_43181, Feb 29 2012, 16:46:43 on linuxx8664gcc)

  tree->Branch("ng",&ng,"ng/I"); // FIXME
  tree->Branch("gE", gE, "gE[ng]/F");

  TRandom r;

    if (! (i%10000) ) {
      std::cout << "Event: " << i << std::endl;     }
    for (int j=0;j<8;j++) {

      gE[j]=r.Rndm()*1000;
      gT[j]=r.Rndm()*1000;

    }
    tree->Fill();
  }
  tree->Write();
  rootfile->Close();
  delete rootfile;
  return 0;
