The following links take you to an emergency patch, called an Engineering Special or ES. These emergency patches are meant for deployments that are actively encountering a specific problem and cannot wait for a formal release to include a fix. An ES receives limited testing compared to a formal release. Installing an ES on a production system poses a risk of instability due to that limited testing. If you are not directly experiencing this problem, wait to install a major, minor, or maintenance release that includes the fix for this issue. If you experience this problem and cannot wait for a later formal release, select the ES that matches the base release of your deployment. The base release is the front part of the ES name. Only install an ES that matches the release that your deployment runs. Always read the release notes or Readme file before running the patch installer.
