Which means it is crashing at that location.
The best solution (though time consuming) is to backup all the data and do a factory default. You'll then need to reconfigure the NAS and restore data from backup.
Do you have any apps? If you do, this approach would also require you to reinstall them. This isn't easy, as the version of Debian the NAS is running has been retired. But there are instructions here on config changes you need to make.
