Hi! Maybe I found a problem with 2.7.0, which made me revert back to my prevoius 2.6.4.
Here it is my log. My pool strategy is failover, from my config file ("failover" : true).

Here above things are going fine, I'm mining on pool0. Then pool0 (mtred) has a problem and cgminer correctly switches to pool1:

It looks like also pool1 (ABCpool) is having a problem, so cgminer starts getting work from, and sending shares to, all the other pools. I've never seen so much spread before (I mean: the activity to the selected pool, pool1, is so little!), but I'm fine with it.

The behaviour remains the same (I cut the log), then the problem: I switch to pool2 (deepbit) sending, as usual, an API request to cgminer. Cgminer obeys ("Connected to
http://deepbit..."),
pool2 (deepbit) has no problem at all (verified), but despite it cgminer keeps on sending shares everywhere! [2012-08-20 23:25:05] Accepted 3d3b8e8b.ce1081bc GPU 0 pool 5

After some minutes, I quitted and reverted back to 2.6.4.
HTH.
Thanks for everything.
