Common dam:sha1 value for multiple assets

[bona]

There is an issue in AEM DAM where multiple assets are sharing the same dam:sha1 value, despite being distinct files. These assets were uploaded via a different server, and when downloaded, they have a file size of 0 KB and most of them has status: Error [Upload failed].

AEM version: 6.5

What could be the cause of these assets having the same dam:sha1 value, and how can this issue be resolved?

Thanks.

@bona same dam:sha1 properties defines asset references. This means, these aren't binary files but just references of a source asset. Makes more sense in the case of language copies, e.g.

en-us assets will be master

fr-fr assets will be binaryless language copies/ references

@diksha_mishra  What would be the case if thousands of assets have the same dam:sha1 value?
