Root gurus
I am using Root 2.23/09 and writing a TTree with three
TClonesArrays, Tracks, Hits, and Pixels. Recently I
suffer unreproducable troubles with root output files.
Though the tree is well behaved while I am running
the writing program, if I close the file and exit and then
reopen the file I am often stuck with a segmentation
fault in trying to look at the TTree, sometimes accompanied
by a message about insufficient memory.
Victor (Perevoztchikov) says he remembers a rootalk
dialog about buffer (basket) size problems. My events
have usually about 16000 Hits, which means members
would come near the 64 Kbytes basket size. Does root
maybe have a problem when variables just overflow a
basket?
I would love to send an example script but I have had
runs of 200 events that work fine and runs of 5 events
that produced an unusable root file. Its frustrating.
Any information or advice would be appreciated.
Thanks
Bill Love
