Broken miner: no more backup pools I have 3 graphics cards running poclbm each with a rate of about 140 MH/s. This has been running since I posted an earlier question ( &quot;No more backup pools left. Using primary and starting over.&quot; ) in August I have not found/created a block in that time.

However every so many hours or every few days (irregularly, but never 5 days uninterrupted), I get the message, "No more backup pools left. Using primary and starting over." 

Is this message effecting my ability to mine, or am I just impatient?
This indicates that your miner couldn't get work from the pool fast enough and so some mining power was wasted. If this only happens occasionally, I wouldn't worry about it. If it happens often enough that it's impacting your mining rate, you may wish to configure a backup pool. If it's happening because your Internet connection is slow or unreliable, there's probably nothing you can do about it.
