It does sound serious. This message should only show up if the files
have changed the checksum after the first initial upload! Something
seems to have tampered with the files on your disk.
How does your installation look? Do you have a replicated archive? In
that case you should be able to recover from this situation using the
bit preservation tools. Otherwise you may have to try to manually figure
out if your arc files are okay. Do you have a backup you can compare

I think in this case the reason you have this problem is the lost
connection you reported earlier. The database update that should have
marked the job 'done' or 'failed' failed to update the database.
Currently, unfortunately you cannot recover from this situation from
within the system. You can shut down the system and manually update the
stattus field of the 'jobs' table in the database. or you can ignore the
seemingly started job - it's harmless.
However, this should not cause the warning you see below. That warning
seems to indicate something has changed on disk.
The bit preservation interface should show you more.
