maximum files list of bparchive -f file.

hi all:
I have a file with the filepath of over 4millions files. When I issue bparchive -p "policy name" -s "schedule name" -k "string to facilitate searching/id the bkp" -L logilepath -f filename on my solaris 10 box. the bparchive takes its time to return the prompt; but there is nothing on the activity monitor nor the logfile, there is not error messages either.

I'm using NBU 6.0 MP7 (yes that old version) but I wonder what is the maximum for the list file (the file with the filepaths). 100K lines, 1 M lines???

Thanks a lot.
