System.Net.WebException: The remote server returned an error: (409) Conflict. (Network Steve Forum)

System.Net.WebException: The remote server returned an error: (409) Conflict.

Hello,

We're trying to upload a lot of data (350+GB) to our on premises instance of SharePoint 2013.

This data is currently on a shared drive and consists of 1M+ documents on probably 10000+ different folders.

I've written a simple multithreaded tool that uploads the files to SP.

The his uses Parallel.ForEach. and works ok with small amounts of data, but when we try it in anger we tart getting this exception

Net.WebException: The remote server returned an error: (409) Conflict.
at System.Net.HttpWebRequest.GetResponse()
at Microsoft.SharePoint.Client.SPWebRequestExecutor.Execute()
at Microsoft.SharePoint.Client.File.SaveBinary(ClientContext context, String serverRelativeUrl, Stream stream, String etag, Boolean overwriteIfExists, SaveBinaryCheckMode checkMode)
at Migrator.Program.UploadFile(ClientContext context, String filePath, Boolean exception) in c

Interestingly, if I ramp up the number of threads, I get a lot more of these exceptions.

Perhaps, more interestingly we seem to get the error always for the same files, at least after two tries.

I can't really see anything on the SP log, at least anything I can make sense out of.

The below seems to happen after the issue occurrs but not sure if this is the case or just an unrelated exception.

Any ideas?

Thanks

Hi Agoney,

From the error message, it seems that you are using client object model to upload the files to SharePoint library.

How did you upload the file to SharePoint?

Please check the links below to see if the code in the links below works for you:
