My team often encounters the following error when attempting to submit a simple "ls" job using the osg-edu.cs.wisc.edu job manager: "GRAM Job submission failed because the connection to the server failed (check host and port) (error code 12)"
When this failure occurs a globus id for the submitted job is not returned. Because the GridShell does not get the globus id it cannot handle the job.
If this problem occurs, the job should be considered a failure and the status should be FAILED.
