JIRA Agile Board slow and Backlog Error

[mburgess]

I seem to be getting a lot of strange issues lately with JIRA.  

- Kanban board showing timeout error often

- Backlog not showing all issues

- The error below when viewing backlog often

Please try refreshing the page, or contact your administrator / Atlassian Support if the problem continues.
