@PassiveIncomeMachine, could you share the following information too, please?

  1. A complete stack trace (pointing to some line numbers in the org.apache.logging.log4j package, etc.)
  2. Layout.json file

For the record, maxStringLength="10000000" looks dangerous to me. Note that it doesn't limit the total JSON document length, but the maximum length of a String-typed field in the JSON document. I would try to keep it way lower.
