Stefan Grroschupf updated NUTCH-15:

    Attachment: timeOutPatch.txt

A patch that reads the timeout from the nutch configuration object and adds the value to the
nutch-default.xml file

> The timeout of the ipc client is hard coded to 10 seconds. 
> Under heavy load it is common that for example that search servers crashs, since they
are just overloaded.
> In  case just one search server crahs  every query took 10 seconds since in any case
we wait for the crashed server.
> To make the timeout configurable would be a fist step, however we may can discuss implement
a client / server similar to the dfs where the client is announcing itself to the server and
the server add dynamically new clients or remove clients that fails for a given time period.
> This would be more confortable for production secarios since crashes are more oftern
under heavy load and in case more server are involved.
