I have now changed the following, correct ?

## node.conn[0].timeo.noop_out_interval = 5
node.conn[0].timeo.noop_out_interval = 0
node.conn[1].timeo.noop_out_interval = 0

# node.conn[0].timeo.noop_out_timeout = 5
node.conn[0].timeo.noop_out_timeout = 0
node.conn[1].timeo.noop_out_timeout = 0

I noticed this:

May  6 08:52:22 manjula iscsid: connection2:0 is operational now
May  6 08:52:22 manjula iscsid: connection1:0 is operational now

Should the above changes instead be:

node.conn[1].xxx
node.conn[2].xxx

I still see the same errors though:

There seem to be about one minute between the failures. One
observation, it's always connection1:0 that fails.
Both target ports are connected to the same switch.

Furthermore, are there supposed to as many processes as this ?
