Writing my own class in root files

I created a named root class rootdouble. I am opening N root files, each one containing an object of rootdouble, named “MergeableCounterValue”. I receive the following complaints regarding rootdouble beginning with the second root file opened:

Warning in TFile::Init: successfully recovered 1 keys
Warning in TFile::Init: file FileN.root probably not closed, trying to recover
Info in TFile::Recover:FileN.root, recovered key rootdouble:MergeableCounterValue at address 426

The files contain also histograms, but there are no complaints regarding the histograms.

Although the information in rootdouble is recovered correctly, I wonder if the complaints have any significance or could be pertinent of some problem.


First - could you attach code with your class? It hard to say what is problem without code.
