Error Trying To Lock Session Data

Post by OleBroseph » Mon Sep 30, 2019 10:19 pm


We upgraded to the newest version of DocuVieware today (3.1.37) using the GdPicture.NET.14.WEB.DocuVieware.dll from the DocuVieware (.NET Framework 4.6) folder in Redist.

We keep receiving an error stating GdPicture.Internal.WEB.DocuViewareCore.Requests.InitRequestCtx: Failed to open session: timeout while trying to lock the session data. We are using the cache file method, and while running the application I can see locks folder inside of the CACHE folder with a single sessionlock file.

Any help on this issue? I've attached a screenshot of the error DocuVieware returns.

You should cross check that you are correctly disposing instanced DocuViewer objects from the server side.
If your problem persists, you should try to replicate it in a small standalone application that you can share with us through our help-desk:

Kind regards,
