Hi everybody,

Ii'm using two servers, one for jenkins master, and one for the slave 
instance 

I'm using Jenkins 1.456 as a main stream version, and was trying to prepare 
an upgrade to 1.518, so i just installed another jenkins master for testing 
puropose, and defined different ports for each one (the main master and the 
test master)

then i added a slave node to the test-master, and i had already a slave 
node for the main master.

i launch each slave by calling a script through ssh, something like

ssh me@my-slaves-server '/home/me/ slave_test.ksh start'

and the script is calling slaves that way

nohup /.../JAVA-6/bin/java -Xms512m -Xmx1024m -Djava.io.tmpdir=/tmp -jar 
/.../hudson_slave/jar/${HUDSON_VERSION}/slave.jar -jnlpUrl 
http://${MASTER_HOST}:${MASTER_PORT}/computer/${SLAVE_HOST}/slave-agent.jnlp 
  

The problem is, each time i launch the test-slave the main-slave goes 
offline and i have this stack trace

ERROR: Unable to launch the slave agent for 
my-slaves-serverjava.io.EOFException
