Whoever is address "1D1ugDJrrifR7WG3TaU1w71yF2wiXmAGqC", something looks to be screwed up in your miner config.  I see a ton of connections from you that keep opening longpoll connections, but rarely request or submit any work.

Yesterday, it looks like you were mining okay-ish (barely; you were only submitting shares for about half of the getworks requested) with a 1-2 Ghash.  Today, the log is just getting spammed with longpoll requests; looks like you're maintaining ~80 open connections, but are hardly submitting any work.  Each time a new longpoll comes out, trying to handle all your connections is causing brief idles for everyone else.

I've temporarily blocked your access to multiclone due to the problems your miners are causing everyone else. Please PM me when you think you have it fixed and I'll re-enable you.
