LiveCycle ES: Workspace Group queue does not refresh automatically to show new tasks

Issue

If you are using group queues in Workspace ES you may notice that new tasks assigned to one of your group queues are not showing up automatically.  The user queues always refresh and show the new tasks automatically, but the group queues do not.

Solution

This issue has been fixed in ES 8.2.1.3 and later versions.  A patch is available to fix this issue in LiveCycle 8.2.1.2. Contact support if you require this patch, to ensure that it is compatible with your environment.

Additional information

If the patch does not fix the issue, check the server log for JGroups messages for more information about the possible root cause.

Also check the Global Workspace admin settings:

in LiveCycle Administration Console, click Services > LiveCycle Workspace ES > Global Administration. Under Export global settings, click Export.

Check the properties defined under server_remoteevents_JChannelConnectionProperties.  These are the connection properties for JGroups that are used to communicate between the server (on which a service event is processed by the RemoteEvent service) and all instances of Workspace ES.

If necessary, change the UDP values for the multicast IP address (mcast_addr), the multicast IP port (mcast_port), and the TTL for the multicast packets (ip_ttl). By default, the multicast IP address and port values are randomly generated and, generally, the values do not need to be changed. However, if your company has any network policies in regard to specific multicast ranges for multicast IP addresses, you sometimes need to change these values.

Note: The TTL must be greater than the number of network switches between the servers in the cluster.  However, if the value is set too high, it can cause multicast packets to travel into subnets, where they are discarded.

Do not change the remaining properties.
