Think you're "Stuck" on "Verifying backend data"?

Hi, I found this thread and a several similar reports about the verifying taking forever.

I am running 2.0.4.23_beta_2019-07-14 on Unraid in a container.
Current backup set is about 1.7TB, using B2.
Backup has been on verifying for a few days now.
Unraid docker usage shows that Duplicati is running at 12% CPU, and one CPU thread thread at near 100%, possibly indicating a tight loop issue.

Server status:

lastPgEvent : {"BackupID":"3","TaskID":3,"BackendAction":"List","BackendPath":null,"BackendFileSize":-1,"BackendFileProgress":0,"BackendSpeed":-1,"BackendIsBlocking":false,"CurrentFilename":null,"CurrentFilesize":0,"CurrentFileoffset":0,"Phase":"Backup_PreBackupVerify","OverallProgress":0,"ProcessedFileCount":0,"ProcessedFileSize":0,"TotalFileCount":2038822,"TotalFileSize":1812991290750,"StillCounting":false}
updaterState : Waiting

Last live profiling log entry is from the 5th, today is the 9th:

Aug 5, 2019 9:15 AM:
Including path as no filters matched: /source/backup/Profiles/DESKTOP-UUIL10M/ProgramData/Adobe/AAMUpdater/1.0/

It is still running, anything I can do help troubleshoot?
