Hi,
I don't see a how to have a random behavior (race condition) here. Are
you sure that you database connection is working and that you are not
getting the sense of some working item just from your browser cache and
the system was instead unable to serve any request?

Have you identified other oddity in the system or do you see anything
strange on the database logs?

Andrea
