Known Issues and Workarounds

Platform
|
|
Due to possible security vulnerabilities, a minimum version of Apache Tomcat 8.5.42 or 9.0.21 is required. It is strongly recommended that you upgrade Apache Tomcat to these versions to mitigate known security issues with older versions of Apache Tomcat.
|
|
If you are upgrading to 8.4.5, it is recommended to set the runAsUser field for the AuditArchiveCleanupNotificationScheduler, AuditArchiveScheduler, and AuditArchiveCleanupScheduler system objects to avoid error messages in the Application log upon platform startup. If the runAsUser is left blank, the schedulers will be inactive. This issue will be fixed in a future release.
