Question

Jetty有一个奇怪的问题。一段时间后，服务请求，CPU使用率达到100％。我发现线程负责，这里有一些在eclipse中采集的堆栈跟踪样本：

SocketInputStream.read(byte[], int, int) line: 113  
ByteArrayBuffer.readFrom(InputStream, int) line: 388    
SocketConnector$ConnectorEndPoint(StreamEndPoint).fill(Buffer) line: 132    
SocketConnector$ConnectorEndPoint.fill(Buffer) line: 209    
HttpParser.parseNext() line: 289    
HttpParser.parseAvailable() line: 214   
HttpConnection.handle() line: 411   
SocketConnector$ConnectorEndPoint.run() line: 241   
QueuedThreadPool$3.run() line: 529  
Thread.run() line: 680

Throwable.fillInStackTrace() line: not available [native method]    
SocketException(Throwable).<init>(String) line: 196 
SocketException(Exception).<init>(String) line: 41  
SocketException(IOException).<init>(String) line: 41    
SocketException.<init>(String) line: 29

这些跟踪是在没有连接客户端的情况下进行的，也就是说，重新启动受影响的线程并再次暂停它以获取堆栈跟踪就足够了。有人有什么想法吗？

编辑：这是相关的，我想知道：How to get Jetty thread dump?

Answer 1

在它执行此操作之前它运行了多长时间？

您是否使用-server开关启动JVM？如果你不这样做，我建议你这样做。

对我而言，这听起来像是一个Jetty错误。也许可以尝试搜索他们的档案。
