Прерывистое исключение шаблона Freemarker, по-видимому, когда под нагрузкой

Question

Мы только что выпустили некоторые изменения в нашем приложении, и сегодня утром у нас периодически возникали некоторые исключения Freemarker.

Наш шаблон Freemarker под названием monitoring.ftl включает header.ftl, который, в свою очередь, включает header_setup.ftl

Как в dev, так и в тестировании мы не сталкивались с этим исключением, и примерно с 9:30 утра это исключение не произошло в Prod (т. Е. Шаблон существует и работает по большей части), но до этогобыло несколько раз, когда исключение ниже было зарегистрировано.И это, похоже, было во время нашей пиковой загрузки.

Итак, мой вопрос: кто-нибудь испытывал Freemarker периодически, не имея возможности найти шаблон под нагрузкой?
