[Condor-users] shadow exception error?

["Jun Wang" <junwang@xxxxxxxxxxxxxx>]

Dear condor-users:

I just installed condor_6.6.11 on our Linux cluster consisting of 12 nodes with NFS system.
When I typed condor_q and condor_status on the master node(central manager) and slave nodes(compute nodes), I got the normal screen output which told me how many jobs are running, etc. and which machines are in my pool. Then I tried to run the test example "sh_loop" under condor-6.6.11/examples as user condor by condor_submit sh_loop.cmd on my master node. The job terminated normally. However, when I tried to submit the sh_loop.cmd on my slave node I got shadow exception error message in file sh_loop.log as below:

Does anybody know the possible reason?
