I am trying to mine solo. What would a backup pool mean in this context?

It would mean your Bitcoin client wasn't responding fast enough.

<p>I have 3 graphics cards running poclbm each with a rate of about 140 MH/s.

# Broken miner: no more backup pools

(Asked by: username_0 on 2013-02-13)

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 ( ["No more backup pools left. Using primary and starting over."](https://bitcoin.stackexchange.com/questions/4454/no-more-backup-pools-left-using-primary-and-starting-over) ) 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?
