Hi Rooters.

I have 3 root files that have no problem when I process them individually.
Those 3 files are all.1.rm10.root, all.2.root, and all.3.root.
However when I try to combine them into 1 files using merge.all.C
 {
TChain ch("lfit1");
ch.Add("all.1.rm10.root");
ch.Add("../all.2.root");
ch.Add("../all.3.root");
ch.Merge("all.lfit1.root");
}
 
I got core dump with the following message.
root [0] .x merge.all.C
Error in <TFile::ReadBuffer>: error reading all requested bytes from file
all.1.rm10.root, got 4903 of 11651
R__unzip: discrepancy with initial size
Error in <TBasket::ReadBasketBuffers>: fObjlen = 31936, nout = 0
Error in <TBranch::GetBasket>: File problem at address:7146713, basket
seekkey=7146713, branch:evt
SysError in <TFile::ReadBuffer>: error reading from file all.1.rm10.root
(No such file or directory)


Do you have any idea?
