Previously, there was an incident due to a mismatch between the local state and the state from the local database: #4437
To prevent such issues from occurring in the future, regular checks can be conducted to ensure that the local state matches the state stored in the local database. A mechanism is being developed to compare the local state and the state from the local database: #4842
But now, in some cases, DiskStateUpdate is written to the local database, but does not appear in the local state. PR to solve this problem: #4868
