* Author: Steve Johnson

* ruby -v: ruby 2.0.0p598 (2014-11-13 revision 48408) [x86_64-linux]

----------------------------------------
I'm not a developer and I'm not interested in upgrading Ruby as a troubleshooting step. I googled the error but have no idea if the solutions I found address this issue.

Environment: Ubuntu 14 with Ruby 2.0.0, Apache 2.4, PHP 5.6, Jekyll 2.4.0, Markdown source with some HTML in source also
Steps to reproduce:

1. rm -rf _site
2. bundle exec jekyll serve
3. check-links --no-warnings .

Expected result: check-links runs without errors
Actual result: check-links starts throwing these while checking files that were authored in HTML:

Problem: ./_site/guides/m1x/other/solr-ee-patches.html
   Link: http://support.magentocommerce.com/
     Response: Too many open files - getaddrinfo

Note: check-links worked fine before I added the HTML-authored files to the project.

Final stack trace:
