Hi,
See TTree::ChangeFile which may be triggered in your case. You may have to increase increase the default limit
TTree::SetMaxTreeSize(very_large_number); or allocate the TFile on the stack reather than heap.
Cheers,
Philippe.

Subject: [ROOT]TFile crash in ~TFile
I get a segmentation violation in ~TFile as it is trying to close my file. The trace back is below.
The line pointed to in my code is 985. However, the error appears to not during |write| but when the TFile is destroyed on leave this scope at the "}".
Other identical jobs run fine. This is the largest data set processed. It worked previously; here I've just added a few more items to output n-tuple for a total of 32. There are 47G available where it's being written which should be plenty and in any case it's seg violation not a out of space error.
Any ideas?
-Thanks, Art S.
code snip:
for(Int_t i=0; i<nHist; i++) {
if(h[i]==0) continue;
h[i]->Write();
}
//write out the n-tuple
tup->write(); <---line 985
}
