about every 10 seconds, our Jenkins reports this error:

三月 20, 2016 10:30:32 下午 org.eclipse.jetty.util.log.JavaUtilLog warn
警告: HttpParser Full for SCEP@56cdbd4f

{l(/99.12.115.91:64512)<->r(/99.12.38.223:6060),s=1,open=true,ishut=false,oshut=false,rb=false,wb=false,w=true,i=1r}

{s=0,h=-1,b=-1,c=-1}

,p=HttpParser

{s=-10,l=0,c=-3}

,r=0}

This error has been around for quite a while. I guess it happened since Jenkins introduced Jetty.

By reading from the Internet, it seems that I could fix this problem by adding below to jetty.xml:

<headerBufferSize>16384</headerBufferSize>

But I can't find where the file jetty.xml is in jenkins home.
Or is there any other way that this problem be fixed?

thanks
