# This script is intended to help Koha libraries affected by Bug 6868 repair |
| 6 |
# their accountlines table; unnecessarily large accountno numbers were entered |
| 7 |
# due to a bug with the writeoff subroutine; this is fixed by enhancement 3498. |
| 8 |
# The accountno has a maximum value of 32767, and once that's reached, fines payments |
| 9 |
# will be applied to multiple fines (resulting in data loss). |
