MID server memory leak caused by long running "Amazon AWS Route53 HD" pattern.Issue MID Server memory gradually increases until the JVM crashes or killed by the Wrapper Service.ReleaseLondon or newer releasesCauseFor Kingston release or older, "Amazon AWS Route53 HD" was using AWS SDK to make API calls to retrieve data from AWS. After upgrade to London or newer releases, if the pattern is not upgraded (due to customization), a pattern step can run into an infinite loop of trying to fetch data from AWS leading to gradual increase in memory usage leading to eventual Out Of Memory situation. From London onwards, we make REST Calls to get data replacing AWS SDK APIs.ResolutionRevert the pattern to OOB release for London or newer.
