jetty error, broken pipe

[alxsss]

Hello,

I use solr 3.4 with jetty that is included in it. Periodically, I see this 
error in the jetty output

I searched web and the only advice I get is to upgrade to jetty 6.1, but I 
think the version included in solr is 6.1.26.

Any advise is appreciated.


Thanks.
