Recently updated my last sles boxes to sles11sp4 / oes11sp3.

I am having an issue where one of my 'client' servers continuously
shows an unknown status on my SMT box.

I have a cron job on the SMT box to get a patchstatus of my client
servers once an hour, and then a job on my client servers to report
back once an hour (a couple minutes after the SMT box job).

I've removed the smt-agent from the client server, ran
suse_register -E, then re-registered it, configured it for smt and then
reinstall the smt-agent.

Still have the issue where it shows an unknown status.

Any suggestions?
