For a while now in my 4 instances (2 Confluence, 2 Jira, latest versions in stages during last months, problem applies to all since Feb 2012) the support tools log scanner hasn't been working. I've removed existing logs, tried scanning different size logs and in none of these attempts has there been any motion on the progress bar beyond 0%, even after 10 minutes waiting.
Just curious, can someone try latest version Confluence or Jira and see if theirs are working?
