I have a strange problem with Jetty. After a while, serving requests, the CPU usage goes to 100%. I have found the thread responsible, and here are a few samples of its stack trace taken in eclipse:
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

Thread.run() line: 680
These traces were taken with no clients connected, that is, it was sufficient to re-start the affected Thread and suspend it again to take the stack trace. Anyone have any ideas?
Edit: Is this related, I wonder: How to get Jetty thread dump?
