Jira Data Center v8,5,4
We are seeing intermittent issues where users are unable to perform Service Desk related tasks.
Upon investigation it looks like that these users are sometimes not being seen as being in the Service Desk Team Role. In fact it says that there isn't anyone in any Roles. We've seen it happen on two different Service Desk Projects.
It doesn't seem to be a configuration issue, directly. Typically clearing cookies and logging out and in, and therefore getting connected to a different Jira Node, resolves the issue. So some Nodes are seeing the proper Role membership and some are not.
I've recycled the Nodes, but on one of the new Nodes I was immediately able to reproduce the problem. Connecting to the other new Node and everything looks fine.
EDIT: Possibly related to this. This references groups, not roles, but it's a similar problem.
