    I was wondering if anyone has come across an issue whereby (on random occasions that can last for a few hours or days) the Telerik RAD web part editor times out when trying to use functionality such as the Image or Document managers?

    One of the products we support uses version v7.01 of the Telerik RAD editor and cannot be easily updated due to the Product being based on a platform with SharePoint 2003 and .net 1.1. The RAD editor is heavily used by the large customer base however on random occasions they find that clicking on either the Image manager or the Document manager for example will cause the opening of the manager window but nothing loading inside the window and instead a request timed out error message is displayed with additional text of there being a server error within the /wpresources application.

    We have a number of web servers and when this request time out error occurs we can confirm that we can independantly hit each of the servers and see the same error but there are absolutely no errors being logged in eventviewer on the web servers or in our custom logs. It is worth noting that we have considered whether or not the issue could be something to do with having too many files in the picture libraries, etc but this does not explain why without changing the content the error disappears for some time before re-appearing.

    Has anyone experienced this issue before or does anyone know of a way of capturing some verbose logging from the Telerik editor that may shed some light into what is going on?

    Hi Manik,

    Your assumption that the problem could be due to the large amount of images that the image manager tries to load is correct. The image manager of RadEditor for ASP.NET (including version 7.0.1) is not able to load quickly a large amount of images due to its interface, as it reads all files in the selected folder at once. This problem was resolved in the new and much enhanced RadEditor for ASP.NET AJAX, the image manager of which offers paging.

    Since you are not allowed to migrate to the new editor, the only suggestion that I can propose is to
    organize the images in folders (for example 100 files in each folder) so that the browser can load the images faster. This should solve the error.

    Best regards,
    the Telerik team
