DynamoDB errors Orleans

Asked by At

I have an application running that gets data from IoT devices, I have started to have problems where my Orleans silo freezes completely, and it only starts again when I pres enter on the command line. When I pres enter it usually presents with some dynamodb errors (I use DynamoDB for persistent storage). I am getting multiple errors with Writing, reading, and check failed exceptions such as:

Amazon.DynamoDBv2.Model.ConditionalCheckFailedException: The conditional request failed ---> Amazon.Runtime.Internal.HttpErrorResponseException: The remote server returned an error: (400) Bad Request.

System.Net.WebException: The remote server returned an error: (400) Bad Request.

Is there any known bugs with DynamoDB or any way I can trouble shoot this further to get more information?

I did not find the anything more specific about the dynamodb errors, but it seems to be caused by the silo freezes.

Apparently the freezing silo command prompt was because of Quick edit mode: https://serverfault.com/questions/314194/why-does-windows-command-prompt-stalls-until-a-key-is-pressed-when-executing-lon

Disabling quick edit mode seems to have solved my problems.
