Solución alternativa

Updated as of April 11, 2022: New patches have been released to prevent BUG-000148146 on some AWS (Amazon Web Services) deployments. The B patches will install over the top of the original patches if you have already installed the originals. If you did install the original patches, please follow the instructions in the tech article https://support.esri.com/en/Technical-Article/000027487 to ensure your system will not encounter a possible problem where ArcGIS Server machines are removed from a site after a machine restart. If you did not previously install the original patches and are only applying the "B" version, the issue should not exhibit itself. The new patches are available at:
