Hi Rene, I did so. Unfortunately on AIX I cannot test now (cern afs cell not responding..) But on SGI INDY I tested it and the problem with reading back the events remains. In an interactive root session I can read and print run & event of the first 2836 events before a seg violation. Every event contains around 40 TClonesArrays (no other containers). The file has 100 Mb (10000 events). It's not a sick event: if I start reading at event 2836 it crashes at event 5672 thus I think there is a buffer overflow somewhere. The problem is absent in batch. Here I can read all w/o any problem. Both the batch job and root-session had a const memory allocation during the reading of events. machine: SGI INDY single processor 256 Mb RAM, IRIX 6.2, SCSI disk or NFS-mount (I tested both) root: version 1.03/08 25 November 1997 ahoi Jobst On Tue, 9 Dec 1997, Rene Brun wrote: > Hi Jobst, > Couild you change you buffer size from 64K to say 16K. > I see that you have a very large number of branches.
