Thread(0x100190360): deadlock (fatal)
Reported by Arun Thampi | October 30th, 2009 @ 04:20 AM
I get this error when I try to crawl URLs from a site. What can cause this? I'm running ruby 1.8.7 (2009-06-12 patchlevel 174) [i686-darwin10] on Mac OS X 10.6.1 with Anemone 0.2.2 The entire stack trace is like so:
I'm digging deeper, but any pointers will be much appreciated!

I have a similar experience of this ticket.
Throwing exception from my code in result.
Please add following flag to your code and retry.
If error in your code, Ruby will throw stacktrace more easy to fix.Thread.abort_on_exception = true

Anemone is a Ruby library that makes it quick and painless to write programs that spider a website. It provides a simple DSL for performing actions on every page of a site, skipping certain URLs, and calculating the shortest path to a given page on a site.
