java - java.io.BufferedInputStream com.logica 上的高 CPU 负载

转载作者：太空宇宙更新时间：2023-11-04 13:54:56

我们有一个 java 程序，它通过 tcpip 套接字连接到远程服务器，并在连续的 while 循环中发送异步消息并接收响应。有 9 个并行线程正在运行并从单个 QUEUE 中提取数据。

每当队列中没有消息时，程序线程会 hibernate 10 秒，然后再次向队列中查询消息。同时，它也每 10 秒向远程服务器发送一次 keepalive 信号。

该程序可以正常运行 1-2 天或更长时间(CPU 利用率为 2-5%)，但之后 CPU 利用率突然变得非常高，达到 99-100%。如果我杀死并再次启动它，它会再次正常工作。

我已经获取了线程转储(使用 jstack)并尝试使用 VisualVM。

下面是我的线程转储。
