Seeing a lot of files with 0 bytes after the import is completed successfully

[Roshan John]

Hi,

   I have been running some test bulk imports and started noticing that a lot of files have been imported with no content (0 Bytes). These are files in sub-folders. If I run the migration just against the sub-folder it works fine. Looking at the Bulk import summary screen, there is a difference between Content Streamed and Nodes Created. 

Content streamed:

2439

Nodes imported:

9604

I am guessing the two numbers should match, if all the files have content associated with it.

When I increased the logging, I noticed an error with S3 ContentWriter. This is happening only on long running imports.

2017-09-12 17:00:57 DEBUG [org.alfresco.extension.bulkimport.impl.BatchImporterImpl:201] - BULKIMPORT: HMH Sci 2009 TN PE PDFs B-Printing/Grade 4_SE_TN_Science_Final pdf/Grade 4_SE_TN_Science pdf 1 of 2/042_4_084619_C1L4.pdf||08127950 Failed to copy content from file:

We are not seeing any errors with S3 connectivity.

Thanks in advance for any advice or next steps.
