Behavior:
When documents are displayed via the SAP GUI, the following error may occur:
TCP/IP error. HTTP error: 500 (Internal Server Error) Error occurred in InfoRequestHandler - Stream is not opened or does not support reading!
Solution:
If this happens, increase the number of possible connections to Content Server.
To do this, open the "DWContentServer.exe.settings" file in the DocuWare Content Server installation (not to be confused with the DocuWare SAP HTTP Content Server).
There change the parameter "MaxCachedDocuments" from 5 to 10, or even 20. After the change, restart the DocuWare services.
