Grails的內存泄漏 - ConcurrentHashMap的

Grails的性能&內存泄漏問題 -Grails的內存泄漏 - ConcurrentHashMap的

我們有對JDK 6.0，可以部署到JBoss 5.1和WebSphere 8.5.5.4環境運行的V2.1.1 Grails的三層Web應用程序。 我們目前有內存問題，經過幾個小時的Seleninum測試運行後，堆空間耗盡。 使用JavaMelody和YourKit工具，我們發現其中一個重大泄漏嫌疑人是'ConcurrentHashMap'，但無法追溯到我們自己的代碼， 以及大多數指向Grails框架庫的嫌疑人。任何提示？ 我們正在尋找有償服務來幫助我們解決這個問題，如果有人在這方面很熟悉。

我們使用的Grails插件列表。是否有列出的插件你已經在過去的內存問題，我們應該避免或更換經歷：

我記得讀過關於jdk 6和併發哈希映射的東西。周圍的問題緩慢不確定是否泄漏內存。你不能嘗試jdk7看看是怎麼回事？ – Vahid

如果您正在尋找支付支持，OCI可以幫助https://grails.org/support.html –

格雷姆，我們已經通過電子郵件發送給OCI，但沒有人聯繫過我們。誰是Grails支持的良好聯繫人？謝謝。 – dhwang

的java.util.HashMap不是併發的，所以如果你是在一個Grails服務使用它或控制器，它可能會獲得併發更新，這會導致各種問題，其中之一可能導致在服務器上運行時發生內存泄漏。

嘗試使用其中一個併發哈希映射代替，如java.util.concurrent.ConcurrentHashMap，並查看問題是否消失。
