SonarQube UI rendering delay (exactly 1 minute!)

I installed SonarQube to help with code quality analysis. I set it up to run behind an Nginx reverse proxy using the instructions on their website. Often I have to wait exactly one minute to load a page. Upon investigation using Google Chrome Developer Tools, I saw that a resource was not loading for exactly one minute. Then, something times out and allows the page to continue to load. Here's a typical example of the problem, where some resources load at the beginning, then there's a one minute delay, then the rest of the page loads:

Typical delay

Sometimes the page loads without any delay.

At first I thought it might be a problem with some JavaScript. Here is an example of clicking around to many pages, and sorting by response time (to see resources might be causing the delay):

Many page loads

I then tried loading a static image, and even that intermittently takes a minute to load.

Intermittent long loads for logo

How can I pin down exactly what component is causing the delay? Could it be the reverse proxy? The SonarQube application? Some JVM problem?

As your 1mn delay happen also with static image (here logo), where there is minimal JVM impact, I would suggest to use curl -L -v against Nginx front end and also directly to SQ HTTP connector.

If 1mn delay never happen when connection to SQ HTTP connector, Nginx / SQ link should be investigated.

If 1mn delay happen also with SQ HTTP connector, SQ JVMs and hosting should be investigated
