我們有一個java程序，它通過tcpip套接字連接到遠程服務器，並在連續while循環中發送異步消息並接收響應。有9個並行線程運行並從一個QUEUE中提取數據。java.io.BufferedInputStream上的高CPU負載com.logica
每當沒有消息存在隊列時，程序線程會休眠10秒鐘，然後再次查詢隊列中的消息。同時，它每隔10秒也向遠程服務器發送Keepalive信號。
該程序運行良好1-2天或更長時間（CPU利用率爲2-5％），但之後CPU利用率突然非常高，達到99-100％。如果我殺了並重新啓動它，它再次正常工作。
我已經採取了線程轉儲（使用jstack），並嘗試使用visualvm。
下面是我的線程轉儲。
