Unable to allocate a managed memory buffer of 268435456 bytes. Available memory may be low.

I am trying to save some big data to a database through a WCF service call. I can not call the service. His mistake:

Unable to allocate a managed memory buffer of 268435456 bytes. Available memory may be low.

public async Task<int> UploadExportPackage(DTO.Upload.UploadPackage package)
        {
            int result = await serviceProxy.UploadResultsAsync(package);
            return result;
        }

Server side configuration:

    

    <!-- 
      Place limits on the amount of data that can be received in one go.
      This helps to protect the server from attack and abuse.
    -->
    <binding name="primaryBinding"
             maxReceivedMessageSize="6000000"
             maxBufferSize="6000000"
             maxBufferPoolSize="12000000">

      <readerQuotas maxArrayLength="6000000"
                    maxStringContentLength="6000000" />
