We have been experiencing an issue since we installed and configured Openfire version 4.1.1 with Spark version 2.8.1, which has been causing it so that when users log in to Spark they will not be able to view any of the contacts or shared contact groups. This initially seemed like it would only be an issue the first time that each user logged in to the Spark client; as they would subsequently log out of and close Spark, log back in and would be able to view all contacts and shared contact groups.
However, we have recently found that the issue intermittently happens for users who have logged in to Spark multiple times previously. In these cases the chain of events still seems to remain the same; the user will initially log in to Spark and will not be able to see contacts or groups; they will then log out of, launch and log in to Spark again and will be able to view the contact groups.
Openfire version 4.1.1 is installed on a Windows Server 2012 R2 Standard server with 12 GB of RAM and 2 processors.
Spark version 2.8.1 is installed on 2008R2 Standard servers with 10 GB of RAM and 4 processors.
Is this an issue that anyone else has previously seen?
