"No more backup pools left. Using primary and starting over." I am not using a pool, I am using my graphics cards mining with poclbm over rpc. i do not understand why I get these messages.

Is this something that is fixable? Should I bother (does it affect the mining in any significant way)?
Presumably, you have no backup pool configured. So if your server doesn't respond quickly enough, poclbm just fails over back to the primary pool. If these are only happening occasionally, I wouldn't worry about it. Anything that momentarily prevents the RPC call from getting a response can do this.
