我有一個運行在Ubuntu 12.04.1 LTS，Java 8u40上的Play Framework 2.4應用程序。一段時間後，我的應用程序停止響應。當我使用top檢查CPU負載時，我看到java進程正在使用100％的CPU。當我運行jstack -F -m <PID>時，我看到循環線程在JVM本機幀之間。JVM本地線程循環並使用100％的CPU
這裏是循環線程的jstack輸出：

後，我從玩2.3升級到2.4和Java 7與Java 8。我不認爲遊戲的升級這個問題開始有什麼有了這個。它看起來與JIT編譯有關。
什麼是這個線程和什麼可能是無限循環的原因，當然我該如何修復/解決方法呢？
謝謝。
這不是offtopic –
8u40不是當前版本，請嘗試更新，看看它是否改變ings – the8472
@ the8472我已經更新到8u66，並沒有幫助。 – neonal
