Portal for ArcGIS 10.8.1 Memory Leak Patch

This patch resolves a memory leak for the Portal for ArcGIS 10.8.1 software component.

Esri® announces the Portal for ArcGIS 10.8.1 Memory Leak Patch. This patch resolves a memory leak for the Portal for ArcGIS 10.8.1 software component. A third party library utilized by Portal for ArcGIS causes the memory leak. This patch is for Windows only because the memory leak does not occur on Linux operating systems. This patch deals specifically with the issue listed below under Issues Addressed with this patch.

A patch for this memory leak is also available for the ArcGIS Data Store software component. Esri recommends installing both patches for your ArcGIS Enterprise deployment.

Important Note: The Portal for ArcGIS 10.8.1 Memory Leak Patch and ArcGIS Data Store 10.8.1 Memory Leak Patch patches are purposefully not available through the Patch Notification tool because the patches need to replace files that are locked while the Patch Notification Tool is running. These patches cannot be installed using the Patch Notification tool and the Patch Notification tool cannot be running at the time of patch installation. The patch installation will terminate any running processes of the Patch Notification tool. To successfully apply this patch, first close the Patch Notification Tool. Then proceed to download and install the patch per the instructions on this page.

As a further consequence of the nature of this patch, the Portal for ArcGIS 10.8.1 Memory Leak Patch and ArcGIS Data Store 10.8.1 Memory Leak Patch cannot be uninstalled. After applying this patch, right-clicking it under Programs and Features > Installed Updates, will not provide an ‘Uninstall’ option.
