problems with TimeoutException and hudson.remoting.Launcher.pingTimeoutSec

[David Gang]

Hi all,
 
We have a failing job 
The exception is 

        ... 10 more
Caused by: java.io.IOException
        at hudson.remoting.Channel.close(Channel.java:895)
        at hudson.slaves.ChannelPinger$1.onDead(ChannelPinger.java:110)
        at hudson.remoting.PingThread.ping(PingThread.java:114)
        at hudson.remoting.PingThread.run(PingThread.java:81)
Caused by: java.util.concurrent.TimeoutException: Ping started on* 
1350445399115 hasn't completed at 1350445639155*
        ... 2 more

 

It looks like it haves a timout after 40 seconds only.

 

I want to configure the variable hudson.remoting.Launcher.pingTimeoutSec so 
that it will wait for 5 minutes.

Is there a way to do it through the UI?

If not how can i configure it?

 

Thanks,

David
