Background
When users has multiple gadgets on a dashboard, multiple reloads are required for the gadgets to display properly.
The console logs shows that a large amounts of request results in Failed to load resource: net::ERR_INSUFFICIENT_RESOURCES
Root Cause
This is a known issue for Jira and also occurs with Atlassian gadgets (e.g. heatmap).
When loading a JIRA Dashboard page, if gadgets are present the browser will make a high number of requests to server for the webresources (CSS, JS) to load the results so the number of web requests can significantly increase dependent on the higher number of gadgets.
For the (failed) status requests, this is likely due to the chrome not being able to handle the large amount of requests resulting in the error "Failed to load resource: net::ERR_INSUFFICIENT_RESOURCES".
Possible Workaround
Reload the dashboard again so that it can reuse the cached resources
Reduce or consolidate the number of gadgets on the dashboard
