Ruby on Rails: Anemone and Redis issues

I'm creating a webcrawler of sorts and when I use Anemone without storage to crawl a site it eventually crashes due to memory issues.

So I installed Redis, redis-rb, etc and changed my code to use the redis storage.. Now I get an error from rails and it does not finish crawling. It does connect to redis, as I can see activity when I monitor it, but it stops the crawl.

I did test redis and it works fine ...

Any ideas???

Your problem is

RuntimeError (-ERR wrong number of arguments for 'hgetall' command):

Somewhere in your code, you are trying to call 'hgetall', but not passing the key or you are passing one too many parameters. Just check your code, and find where you call that command, and pass the correct # of parameters (1)
