As I suspected, the kernel stopped reporting the size of /dev/sdb, and ddrescue is using the maximum size (9223 PB). You will need to power-cycle /dev/sdb, reboot, or provide ddrescue the right size with the '-s' option. (And maybe use the '--complete-only' option in subsequent runs).

    errsize:     2355 TB,  errors:       8  (  0.02%)
non-trimmed:     2355 TB,  in 2193946 area(s)  (  0.02%)
  non-split:         0 B,  in    0 area(s)  (  0%)
 bad-sector:     1123 MB,  in 2193938 area(s)  (  0.00%)

Ddrescue 1.17 treats this case specially bad because of the way it marks failed blocks. Maybe you could update to a newer version.
