Description

I try to load "https://atlas.torproject.org/#search/chaos", by bookmark, or by visiting "https://atlas.torproject.org/" and typing 'chaos' in the search box (which goes to the previous URL).

Atlas says:

"Backend error!
The backend server replied with an error to your query. This probably means that you did not properly format your query. If your query was properly formatted it may mean that there is an issue with your browser/add-ons. Please report which browser/addons/etc. you're using to the bug tracker."

Browsers have no add-ons (the statement about a search error like this possibly being an issue with browser seems to be a misdirection). Browser is OmniWeb 5 (Apple webkit), Safari 5.1.8 (Apple webkit), both on Mac OS 10.6.8. Same page source is seen when visiting the search URL with wget or curl.

Fixed by restarting Tomcat on the back-end server. Leaving this ticket open until tomorrow to find out what caused this problem.

Looks like the Tomcat running Onionoo ran out of heap space, causing this problem. Changing component to Onionoo to further investigate.

Allowing Tomcat to use up to 512M on the heap solved this problem. Closing.
