I have developed a client tool to access walrus using AWS SDK for .Net. I get a problem when upload files with long file name (many in Chinese, each Chinese character needs three UTF-8 bytes). The upload fails, but the bucket cannot be open any more (the error message is : Length cannot be less than zero. Parameter name: length.).

Then I tried JetS3t, it cannot open those buckets either. Another similar problem is when cancel uploading progresses, the corresponding bucket cannot be opened either.

What is the problem?

The cloud-debug log information:
