Bazza,

I tried all you suggested, still doesn't work.

And I tried to remove the node, and system post warning there are jobs associated to the node, I ignore the warming and removed the node, then add the node again, issue new jobs to the node , no job could be executed now, with an error message which can't be read,something like---'???&#???k???'

Anybody has some clue here, pls advise.

Thanks
