When multiple users run pipelines concurrently in Model Studio, the following unexpected behaviors might occur in the user interface (UI):

• Nodes enter a Running state even after the pipeline runs to completion.
• When a user reruns a pipeline or a node after making changes to it, the nodes run indefinitely.

To circumvent this issue, switch from the Pipelines tab to a different tab (for example, the Data tab) or a different section of the UI and then switch back to the Pipelines tab.
