Hi!
I think that usually indicates that the system is running low on available resources, such as memory (RAM). This can happen when working with large datasets or complex workflows.
Some tips:
- If the workflow is large and complex, try breaking it down into multiple smaller workflows. Process and save intermediary results as files, then load them in subsequent workflows to continue processing.
-By default, Designer uses 25% of the RAM on the computer on which it is installed. When processing a workflow, Alteryx adjusts to the memory available on the computer.
Memory Limit can be configured in 3 areas:
(Administrator) System Settings: This setting lets an administrator set the default memory usage for an Alteryx Server install. If you're an administrator, only make changes to this setting if necessary. The default value works well for most scenarios.
User Settings: This setting lets you set the memory usage for your Designer instance. These changes only affect the machine the setting is changed on.
Workflow Configuration: (Runtime tab) This setting lets you edit the memory usage for a specific workflow. Changes made here only apply to the workflow that is open. This makes it possible for you to allocate more memory for memory-intensive processes (for example, spatial, predictive, etc.) as needed so the workflow can run smoothly and ideally, more quickly.

- Reduce Data Size: Filter or sample your data to work with a smaller subset if possible.
