  Hi maliming,

  I have shared the controller's full code and the respective DTO which used in creation API(CreateAsync method in controller is used for creating)

  hi

  Can you try the following solution:

  1. Remove public IFormFile[]? Files { get; set; } and test again.
  2. Use IRemoteStreamContent to replace the IFromFile and test again. https://abp.io/docs/latest/framework/architecture/domain-driven-design/application-services#working-with-streams

  Thanks

  Hi maliming,

  1. Replaced the IformFile with IRemoteStreamContent and load testing is in progress, will update here once load testing is over
  2. How do you think this will resolve the issue?

  Thanks

  hi

  The client has disconnected

  A task was canceled.

  The errors look like the browser request was canceled during the file upload process or the http request,

  Hi maliming, The API randomly shuts down and re-starts automatically in production. Because of this there is considerable downtime and our customers are severely affected. We have reported this issue several times and there had not been proper fix, response or support. I would like to seriously escalated to this and would request an immediate response from you. Please refer the logs and provide us a solution in an hour or two max. There are too many 499 errors in the API. Please let us know more on this.

  hi

  The log shows that an error occurred during the process of ReadFormAsync/ReadAsync. It has nothing to do with the abp code. It is related to IIS. You can try switching to outofprocess mode and try again.

  Change the hostingModel="outofprocess" in web.config file.
