Problem

When JIRA server is open for public, JIRA threads has reached 100%, CPU usage spike at 90% - 100% and become unaccessible.

A lot of the following appears in the atlassian-jira-http-access.log:

"GET https://jira.atlassian.com/issues/ HTTP/1.1" - - - - "Feedfetcher-Google; (+http://www.google.com/feedfetcher.html; feed-id=xxxxxx)"
"GET https://jira.atlassian.com/issues/ HTTP/1.1" 200 xxx xxx - "Feedfetcher-Google; (+http://www.google.com/feedfetcher.html; feed-id=xxxxxxx)"

Cause

The problem was one user had configured a Chrome plugin for RSS with the url of his/her filter (/issues/?filter=nnnnn). This plugin on the browser provoked requests from FeedFetcher-Google.

Resolution

  • Block the requests on Proxy or Web server.
