I localized the origin of this problem. The warning occurs in the TTree::Fill(). I think, it appears on the stage then filled buffer (defined in TBranch) is saved on the disk. Varying the size of this buffer I change the appearance of warnings reading the same set of raw files. Best wishes, Yuriy. > Dear Valeri, > > Thank you for suggestion.
