This is using SuSE SLES 12 servers. Every once in a while, expect to see the following errors logged in the /var/log/messages,
serverA rhn_check: XMLRPC ProtocolError: <ProtocolError for susemanager01.abc.corp /XMLRPC: 500 Internal Server Error>
serverA systemd: rhnsd.service: Unit entered failed state.
serverA systemd: rhnsd.service: Failed with result 'exit-code'.
rhnsd is Spacewalk Server daemon. Look like it has to coordinates with rhnsd.timer and SuSE Manager.
What's went wrong with this service? could it be the SuSE Manager problem/
Thanks in advance.
