Dear MJ, for me it also bug for medium and huge files. (ex : 100 files of 20Mo, or 50 files of 2Mo) my laptop have 2Go Ram, 120GoHDD, CPU Core2Duo... and the bug is the same when data size is > or < of the remaining free memory. same issue on the cluster with 750Go free disk space, and 1 or 2 Go Ram per node. so I'm not certain it's a memory space issue.

One 'easy' solution is to do a 'fast merge' with gjm and the to use a TChain under ROOT to post-process your (multiple files) data.
