SUSE Manager 3.1
spacewalk-java-lib (


In the web-UI, in the section "Admin" --> "Task Schedules"

Clicking on, for example, "mgr-sync-refresh-default" and then changing the schedule and selecting "Update Schedule" makes an error appear:

The scheduling service appears down. Please contact your SUSE Manager administrator.

And the schedule time does not change.

/var/log/rhn/rhn_taskomatic_daemon.log shows:

INFO | jvm 1 | 2018/06/21 13:25:43 | Jun 21, 2018 1:25:43 PM redstone.xmlrpc.XmlRpcDispatcher writeError INFO | jvm 1 | 2018/06/21 13:25:43 | WARNING: redstone.xmlrpc.XmlRpcException: The method cannot be found. Signature: redstone.xmlrpc.XmlRpcArray

Rolling back to the previous spacewalk-java-lib spacewalk-java-lib- fixes the issue.

Updating to: spacewalk-java-lib- makes it fail again.


A bug was opened to address this issue and a fix is already available. As a workaround, users can stay/roll back to the version mentioned before. Otherwise, the next maintenance update will include a fix. In urgent cases, a PTF may be requested.


Some commits were missing in the latest update for spacewalk-java. Those will be included in the next maintenance update.
