Hi, 

I just configured slick upload for my project but am not able to upload files larger than about 35-40MB. It works fine for small files.

The UI behavior is as follows: 

The file starts uploading at a decent rate but the rate continues to fall till about 200b/s or so. At this point uploading stops even though only about 1% of the file has been uploaded and when I check the folder where I upload files the file cant be found.

My web.config is as below: 

 <sectionGroup name="slickUpload">

      <section name="uploadParser" type="Krystalware.SlickUpload.Configuration.NameValueConfigurationSectionHandler, Krystalware.SlickUpload" />

      <section name="uploadStreamProvider" type="Krystalware.SlickUpload.Configuration.NameValueConfigurationSectionHandler, Krystalware.SlickUpload" />

      <section name="statusManager" type="Krystalware.SlickUpload.Configuration.StatusManagerConfigurationSectionHandler, Krystalware.SlickUpload" />

    </sectionGroup>

 <slickUpload>

    <uploadParser handleRequests="false" />

    <uploadStreamProvider location="C:\RebatesUpload\SlickUploadFolder" existingAction="Overwrite" />

    <statusManager manager="Custom" type="ZSAssociates.RebateDesigner.Web.SlickUploadStatusManager,ZSAssociates.RebateDesigner.Web"  />

  </slickUpload>

 <httpRuntime maxRequestLength="2097151" executionTimeout="3600"/>

On checking the status of the upload in the uploadcomplete event in the code behind i get the following:

AllErrors: Nothing

ErrorMessage: Exception of type 'Krystalware.SlickUpload.UploadException' was thrown.

Reason: Disconnected {3}

State: Terminated {2}

I work on VS 3.5 SP1 and on a IIS6 environment. 

Fixed this by changing the following:

 <slickUpload>

        <uploadStreamProvider location="C:\RebatesUpload\SlickUploadFolder" existingAction="Overwrite"  />

    <statusManager manager="Custom" type="ZSAssociates.RebateDesigner.Web.SlickUploadStatusManager,ZSAssociates.RebateDesigner.Web"  />

  </slickUpload>

TO

 <slickUpload>

    <uploadParser attachEvent="BeginRequest" ></uploadParser>

    <uploadStreamProvider location="C:\RebatesUpload\SlickUploadFolder" existingAction="Overwrite"  />

    <statusManager manager="Custom" type="ZSAssociates.RebateDesigner.Web.SlickUploadStatusManager,ZSAssociates.RebateDesigner.Web"  />

  </slickUpload>

We are also facing the same issue, but for IE only. It is showing 100% file upload but after that showing disconnected error.

Please help us in solving this issue.

Thanks for replying,

we are using version. 4.1.1.21510.

Apart from the upload failure issue, when we tried to cancel the file upload in IE then upload get stuck.

Regards
