in /mtpt/ntfs, we have files of size 2gb to 5gb and they are getting copied and while copying filesize of 191gb it fails.

on the monitor we get below

GNU manual here says that there is a limit of 8GB for file sizes, so you should be ok there, unless you happen to have a file bigger than that among the other smaller ones you mention. If you need larger files you could change the tar format to POSIX with the tar --format option.

If that's not the case, are you reaching the end of the tape cartridge perhaps? That does seem more likely from the messages you see, it seems to me.
