"Logon to the remote SLD with "http://<host>:<port>/sld" and
navigate to 'Administration --> Details --> Data Suppliers' and check
whether the 'RFC server threads' are running. They are very likely not started
correctly. Pay attention to the 'Gateway Host' and 'Gateway Port' entries
displayed there. Verify whether they are correct.
You can change 'Gateway
Host' and 'Gateway Port' settings with 'Administration --> Settings -->
Section datasupplier'. Leave the fields empty to use the defaults. Restart the
SLD after that.",

IF it means the RFC server threads running?
