have they not patched this since 2013? This kind of excessive logging is a serious issue in prod envs.  Is turning OFF the only option? Is there no "varied" levels of logging?

Hello

We are using jetty 8.1.14.v20131031 on Java 6.

We are seeing the following warning (When we have a server load) . The warning gets repeated thousands of time and this is slowing down our server and causing timeouts. 

2014-06-11 07:18:03,500  [qtp1653858092-49 Selector7] WARN  org.eclipse.jetty.io.nio - Dispatched Failed! SCEP@4a18198b{l(/10.65.30.11:11500)<->r(/IP:PORT),s=-1,open=true,ishut=false,oshut=false,rb=false,wb=false,w=true,i=0}-{AsyncHttpConnection@74351aad,g=HttpGenerator{s=0,h=-1,b=-1,c=-1},p=HttpParser{s=-14,l=0,c=0},r=0} to org.eclipse.jetty.server.nio.SelectChannelConnector$ConnectorSelectorManager@733d7210

The problem is quite similar to the following stack exchange thread. - http://stackoverflow.com/questions/16592537/jetty-8-1-flooding-the-log-file-with-dispatched-failed-messages.

Is turning off the warning the right solution?

Does this issue get resolved if we move to Jetty9 from Jetty 8. 

Right now we are not in a position to move from Jetty 8 to Jetty9 as this involves moving from Java 6 to Java 7 and we do not want to do that move immediately due to other pressing priorities. 

Is this a known issue and Is there a patch for the issue.  Is there a solution without moving from Jetty 8 to Jetty 9 .

Warm Regards
