>             Project: Nutch
>          Issue Type: Bug
>          Components: fetcher
>    Affects Versions: 1.10, 1.11
>            Reporter: Leon Misakyan
>
> Hi, as I can see in 1.11 release ProtocolFactory class still has an issue in 
> getProtocol method. This is because every fetcher thread has its own 
> ProtocolFactory instance (this.protocolFactory = new ProtocolFactory(conf); 
> in FetcherThread constructor.)
> So have this method synchronized is useless, because each thread has its own 
> monitor.
> In our project we have issue of having multiple Protocol instances.
> Issue can be fixed if getProtocol method will use shared conf instance as 
> lock object or by having one ProtocolFactory for all fetcher threads.
