Summary

When accessing the instance health page, it will POST an AJAX request to execute the health checks. The instance health page will then periodically query the results to see what has completed and is supposed to update the page as this occurs.

Environment

Confluence 6.1 (currently unreleased).

Steps to Reproduce

1. Browse to the Instance Health Page
2. Wait for health checks to complete

Expected Results

As each check completes it is updated periodically to the page (as they run in an executor of 8 threads)

Actual Results

The page waits until the one long running check (end of life in this case as 6.1 is unreleased) to complete until the other checks are updated in the page.

Notes

It appears this is because we put all the checks into one 'process' and run them sequentially rather than in parallel as per the the intended design.
