| ID | Known Issue | |||||
|---|---|---|---|---|---|---|
| 111651 Return | The error, "Attempting to deserialize an empty stream", sometimes occurs when you attempt to build a Web Site project using Measurement Studio controls. On Microsoft Windows Vista x64, when using Visual Studio 2008 without Service Pack 1 installed, the error "Attempting to deserialize an empty stream" occurs when you attempt to build a Web Site project using Measurement Studio controls. Workaround: Upgrade Visual Studio 2008 to Service Pack 1.

| |||||
| 133220 4B89AJ00 Return | Network variable performance decreases when machines hosting the reader, writer, and variables are mixed between Logos and LogosXT. Logos is the National Instruments proprietary protocol for inter-process communication that is used by NI-Publish Subscribe Protocol ( psp:). Performance is especially degraded when the writer and network variable host use LogosXT and the reader that attempts to read the network variable uses Logos. This issue occurs for all reader classes.Workaround: For optimum performance, National Instruments recommends that all machines accessing network variables, including the machine that hosts the variable, should use LogosXT. If using LogosXT on all machines is not possible, you should disable LogosXT. You disable LogosXT by adding a DWORD value named DisablePSPXT to the registry key HKEY_LOCAL_MACHINE\SOFTWARE\National Instruments\LogosXT and setting its value to 1. If you must use a mix of Logos versions, you can reduce the performance loss by using Variable Manager. Use Variable Manager to configure a sufficiently large server-side buffer for the network variable.
