Grails утечка памяти - ConcurrentHashMap - Отличная библиотека

Grails производительность & вопрос утечки памяти -Grails утечка памяти - ConcurrentHashMap

У нас есть v2.1.1 Grails 3-уровневой веб-приложение, которое работает на JDK 6.0, который может быть развернут на Jboss 5.1 и WebSphere 8.5.5.4 среды. У нас в настоящее время проблема с памятью, пространство кучи истощается после нескольких часов испытаний Seleninum. С помощью инструмента JavaMelody и YourKit мы обнаружили, что одним из крупных подозреваемых в утечке является «ConcurrentHashMap», но он не может отследить его до нашего собственного кода, и большинства подозреваемых, указывающих на библиотеки рамок Grails. Любой отзыв? Мы ищем платный сервис, который поможет нам решить эту проблему, если кто-то знаком в этой области.

Список подключаемых модулей Grails, которые мы используем. Есть ли какие-либо из перечисленных плагинов вы столкнулись с вопросом памяти в прошлом, что мы должны избежать или заменить:

Я помню что-то читал в отношении jdk 6 и параллельной хэш-карты. Проблемы вокруг медленного неуверенного, если утечка памяти. Можете ли вы не попробовать jdk7 посмотреть, как это происходит? – Vahid

Если вы ищете платную поддержку, OCI может помочь https://grails.org/support.html –

Грэм, мы отправили по электронной почте и вызвали в OCI, но никто не связался с нами. Кто хороший контакт для поддержки Grails? Спасибо. – dhwang

java.util.HashMap не одновременно, поэтому, если вы используете его в службе Grails или контроллер, вероятно, получат параллельные обновления, что вызовет множество проблем, одна из которых может привести к утечке памяти при работе на сервере.

Попробуйте использовать одну из параллельных хеш-карт, например java.util.concurrent.ConcurrentHashMap, и посмотрите, не исчезла ли проблема.
