About 2 weeks ago our team started noticing that Jira was acting weird - suddenly we couldn't reorder tickets within a column, and creating new tickets became unbearably slow as saving would take up to 30 seconds. We've manually re-indexed several times, with no effect (in fact even re-indexing takes much longer than it used to).
One thing did change around that time, we started using Confluence. Not sure if that's relevant but thought I'd mention it.
Has anyone encountered these symptoms? Any advice?
