Dear Ross,
Thanks for your help.I`m sorry I ignore the following message in the log
file :
Filesize limit exceeded
I find similar question has beed asked by MURAT CETINKAYA.My file system
is ext3, with 2TB file size limit.
Is there anyway to break through the 2GB limit if I don`t want to split
my job up into too many chunks?
