azure-sdk-for-net: Azure.Storage.Blobs UploadAsync raises System.ObjectDisposedException: Cannot access a disposed object.
When I try to upload different files, I get the following error:
System.ObjectDisposedException: Cannot access a disposed object.
Object name: 'SslStream'.

While the error is sporadic, in some cases it always occurs for the same file. I couldn’t figure out the charecteristics of the specific file, but it is not the file size or file name. It happens with small files (less than 1 MB) or larger files (300 MB).
This is the code I use to upload the file:
var serviceUri = new Uri(BlobConnectionString);
var blobServiceClient = new BlobServiceClient(serviceUri);
var container = blobServiceClient.GetBlobContainerClient(ContainerName);
var blobClient = container.GetBlockBlobClient(fileName);
using (var fileStream = File.OpenRead(fileName))
{
var blobUploadOptions = new BlobUploadOptions
{
TransferOptions = new StorageTransferOptions
{
InitialTransferSize = BlockSize,
MaximumConcurrency = Environment.ProcessorCount * 2
}
};
await blobClient.UploadAsync(fileStream, blobUploadOptions);
}

I’ve been hitting this issue when trying to download blobs in parallel. Does this fix potentially also address downloads?
This issue would be fixed in the next Azure.Core release in the beginning of February. You can use steps from https://github.com/Azure/azure-sdk-for-net/blob/master/sdk/core/Azure.Core/CHANGELOG.md#added-2 as a temporary work-around.
I’m currently migrating some code from the Storage SDK v9 to v12. During testing I’ve been seeing this issue for both blobs and queues. Here’s an example stack trace from
QueueClient.SendMessageAsyncin case it helps. Feel free to contact me internally if you want more information, as we hit this fairly regularlyThank you for your feedback. Tagging and routing to the team best able to assist.
