Long shot, assuming you still have the core dump:

Find out which program failed.
file core

Look for error message towards the end of the core dump. This method does not always work. A debugger is better!
strings core | tail -100


Other ideas:

If it is a cron, check root mail for messages.

Check system logs and hardware logs for error messages at the time of failure.

Try "fuser" on the tape device in case something is still using it.

Try the find on its own with output redirected to /dev/null in case it is failing on a bad file and killing the pipeline.

Name
       cpio - format of cpio archive

Description
       The header structure, when the option of is not used, is:
       struct {
		  short   h_magic,
			  h_dev;
		  ushort  h_ino,
			  h_mode,
			  h_uid,
			  h_gid;
		  short   h_nlink,
			  h_rdev
			  h_mtime[2],
			  h_namesize,
			  h_filesize[2]'
		  char	  h_name[h_namesize rounded to word];
       } Hdr;
       When the option is used, the header information is described by:
       sscanf(Chdr,"%6o%6o%6o%6o%6o%6o%6o%6o%11lo%6o%11lo%s",
	     &Hdr.h_magic, &Hdr.h_dev, &Hdr.h_ino, &Hdr.h_mode,
	     &Hdr.h_uid, &Hdr.h_gid, &Hdr.h_nlink, &Hdr.h_rdev,
	     &Longtime, &Hdr.h_namesize,&Longfile,Hdr.h_name);
       The  Longtime  and  Longfile  are equivalent to Hdr.h_mtime and Hdr.h_filesize, respectively.  The contents of each file are recorded in an
       element of the array of varying length structures, archive, together with other items describing the file.  Every instance of h_magic  con-
       tains  the constant 070707 (octal).  The items h_dev through h_mtime have meanings explained in The length of the null-terminated path name
       h_name, including the null byte, is given by h_namesize.

       The last record of the archive always contains the name Special files, directories, and the trailer are recorded with h_filesize  equal	to
       zero.
