I'll second this, I've gotten it about 5 times in the past 5 hours w/ Diablo on a GTX460, I also have cpuminer-0.7 going and got a few "not enough semaphores" or some such. Most of the time Diablo recovers and keeps going, once it went like 20min without doing any work before I killed it.
Should I have a separate account/worker set-up for the cpuminer? I currently have them both logged in to the same user.
Also, I think everything is fine, but should I be expecting more than ~8Mh/s out of an i7 860 and 44Mh/s out of a GTX 460?
You can run many miners on same account, it's ok.
Today i'll add the option to create new workers.
This table says that you should get ~68 MH/s on GTX460 @ 1350 MHz. Looks like you should try another miner.
