Subject RE: Exec Connection Not Closing
Date Mon, 22 Feb 2010 18:02:08 GMT
I changed the ant task to use sshexec instead of exec with ssh as the
executable.  I still have the seemingly random hung process.  I executed
the ant task from outside cruisecontrol and it completed successfully.
The last time I found a hung process I grabbed a thread dump and am
including it here.  Thanks for the suggestions and if there are any
other ideas I'd love to hear them.

Thanks,
Barry

I am using CruiseControl and never saw CruiseControl hanging because a 
build is hanging. However if CruiseControl is configured with only
one thread, only one build can run at one time.

You could use the <sshexec/> ant task instead which is shipping with 
ant, and requires jsch.
Maybe the underlying problem is that sudo is now configured to request a

password ? or your remote user is expired ?
You should try to run this ssh command by hand to see what is wrong.
