Error when you write more than 4 MB of data to Azure Storage: Request body is too large

Original product version:   Storage Account Management
Original KB number:   4016806

Symptoms

Assume that you try to write more than 4 megabytes (MB) of data to a file on Azure Storage, or you try to upload a file that's larger than 4 MB by using the SAS url (REST API) or HTTPS PUT method. In this scenario, the following error is returned:

Code : RequestBodyTooLarge
Message: The request body is too large and exceeds the maximum permissible limit.
RequestId:<ID>
MaxLimit : 4194304

Cause

This error can occur if the block size limit for the service version you run is exceeded. For example, versions prior to 2016-05-31 have a 4-MB block size limit per call to the Azure Storage service. Newer service versions support larger block sizes. For more information, see the following articles:

Workaround

If your file is too large, you must split it into chunks. For more information, see Scalability and performance targets for standard storage accounts.
