I use this site to locate latest release AMI for ec2.
https://cloud-images.ubuntu.com/locator/ec2/
Recently, I have updated my AMI from 20190514 release to 20190816. I have tomcat server in the instance. Observed that catalina logs are showing folllowing error :-
2019-09-06 10:11:07,219 localhost-startStop-1 ERROR Unable to write to stream
UDP:localhost:514 for appender SYSLOGappender:
org.apache.logging.log4j.core.appender.AppenderLoggingException:

processing Appender SYSLOGappender
org.apache.logging.log4j.core.appender.AppenderLoggingException: Error

Where can I find what just changed between 20190514 and 20190816 release?
