Remarks
If Fabric Mirroring, the source SQL database transaction log is monitored. If the transaction log is observed to be full and the log reuse reason is REPLICATION, the database will automatically be reinitialized to Fabric to allow the transaction log to be truncated. During this special reseed state, a database snapshot is sent to Fabric again, then incremental replication resumes. The reseed_state column in sys.sp_help_change_feed_settings indicates the reseed state.
