DisconnectFromSystem API undeploys on windows target even though undeploy_system_definition is set to falseWhen the DisconnectFromSystem API is called with undeploy_system_definition set to false, it undeploys the system on a windows target instead of disconnecting, causing subsequent call to the ConnectToSystem API to fail with an unexpected error.
Workaround: There is currently no known workaround for this issue. |

The system definition deployed to the VeriStand Project Explorer Gateway gets undeployed when the project is opened in the VeriStand applicationWhen a system definition is deployed to the VeriStand Project Explorer Gateway by a VI, .NET, or Python program, it will become undeployed if the project is subsequently opened in the VeriStand application. Workaround: If the Gateway Project services are not needed, start the Gateway by running veristand-server before performing the deploy operation.

FMU Execution Causes Segmentation Fault on Linux RT when Stack Size Limit Is ExceededRunning an FMU model in VeriStand on Linux Real-Time targets results in a segmentation fault if the default stack size limit of 256 KB is exceeded, due to a stack overflow.
Workaround: For VeriStand 2023 or later, increase the thread stack size by editing the lvrt.conf file located at /etc/natinst/share and setting: PosixThreadStackSizeLimit = 2048 This increases the stack size to 2 MB, helping prevent overflow during FMU execution.

Incorrect deployment status shown in VeriStand UI on disconnecting the deployment on RT TargetWhen a System Definition is disconnected using the DisconnectFromSystem .NET API or the VeriStand Disconnect step with undeploy set to false, VeriStand UI incorrectly changes the status from 'Connected' to 'Idle'. This misleading status may suggest the System Definition has been undeployed, although it remains deployed.
Workaround: This is only a UI display issue; the disconnect workflow itself is not impacted.
