Client error
« on: December 23, 2011, 09:20:22 AM »

hello,
     I ran a job, and got all of the results at the client. but after the client gave all the results, it start to reconnect to the server.
 

     I found the log in the log file as follow:

     2011-12-23 16:04:17,239 [WARN ][org.jppf.client.ClassServerDelegateImpl.run(157)]: [driver1] caught java.io.EOFException, will re-initialise ...

Hello,

It is possible that something happened in the server that broken the network connection with the client.
Could you add the following lines in the logging configuration of the server (log4-driver.properties):
Code: [Select]
log4j.logger.org.jppf.server.nio.StateTransitionTask=DEBUG
log4j.logger.org.jppf.server.nio.classloader=DEBUG
This should provide additional information in the server's log and maybe give us clues as to what is happening there.

Sincerely,
-Laurent
