Hi,
I am using root version 2.25/03 on a sun running Solaris 2.6. I've just
started to play with some hbook files produced; converting them to root
using h2root and want to do some analysis with these.
The hbook file is 6 Mb and the root one is 1.5M:
5.7M b0pi0pi0-382459-382459.hbook
1.5M b0pi0pi0-382459-382459.root
I got a very disconcerting warning from root when after opening the
file file and trying to load it into memory (I wanted to look at an
ntuple):
root [1] Error in <TBuffer::ReadObject>: object tag too large, I/O
buffer corrupted
Error in <TBuffer::ReadObject>: object tag too large, I/O buffer
corrupted
Error in <TBuffer::ReadObject>: object tag too large, I/O buffer
corrupted
*** Break *** segmentation violation
Using another SUN system (Solaris 2.6) root 2.23 will open other root
files (from hbook files made by the same analysis code).
Re-building the first file worked (on the same system using the
same h2root binary); root gave no errors when on opening the file I tried
to display the content of the ntuple (this is what went wrong
before). Has anyone encountered similar errors on a regular basis or was
this just some freak one-off that will be unrepeatable or very
infrequent? All other times that I have used h2root have yielded no
obvious problems whatsoever.
I just thought I'd ask ... as I will have quite a lot of hbook file
conversions to do in the coming month.
Thanks
Adrian
