由於一段時間以來我們在Glassfish 3.1上運行的Web應用程序出現嚴重問題。應用程序通過jms進行異步通信。我們的本地服務通過JBossNetty進行通信。由於線程被阻塞導致的性能問題
問題是，我們的Web應用程序的每個請求都會打開一個新線程。沒關係，但線程永遠不會關閉。幾個小時後，由於被阻塞的線程，系統掛起。
一些提示爲什麼線程被阻塞？我附上了下面的線程轉儲。
Full Java Thread Dump Java HotSpot(TM) 64-Bit Server VM 21.0-b17 Oracle Corporation

關於唯一的真正的治癒是「不去做」。與你的請求相反，每個請求創建一個線程真的是*不*很好。 – 2012-04-11 05:27:15
我必須同意@JerryCoffin。不斷創建，終止和銷燬線程效率低下，浪費，速度慢，容易出錯。處理線程終止的最佳方式是不做。將請求排隊到一個線程池。 – 2012-04-11 07:32:17
