When a Platform Analytics workspace loads a list visualization with 'maximum rows' configured to be a very high number leads to exhausting the JVM heap and causing node restarts and Out‑of‑Memory errors. Note: This property is actually the number of records to display per page and not the total number of records to be fetched by the list. Steps to Reproduce 1. Open a Platform Analytics workspace and add a List visualization that queries a table with a large record count. 2. Set the visualization’s **Maximum rows** field to a high number (e.g., 10 000). 3. Load the visualization; the client sends a POST to /api/now/uxf/databroker/exec. 4. Observe the node OOM and restart events caused by the Rhino parsing of the large JSON payload.
The recommendation is to upgrade to the latest version of the Data Visualization from the App Store (version 28.5.4 for Zurich and version 29.1.3 for Australia). This includes a fix that improves handling of large result sets in list visualizations. If unable to upgrade to the latest version, follow the below guidance: If the Data Visualization plugin version is 28.5.0 for Zurich or 29.1.0 for Australia then the issue could be coupled with another PRB - PRB2038106. If this is the case please refer to KB3100924. If the plugin version is different than the one mentioned above or if the issue persists after applying the workaround mentioned in the above KB (KB3100924), then there is a list data visualization where the value 'maximum rows' property is very high. Change the value to be in the range of 10-20 (ideally it should be below 100). This property is actually the number of records to display per page and not the total number of records to be fetched by the list, so this could have been misunderstood and configured wrongly.
