Uhhhh, what's going on?

I got this on an E5620 with -t 4 -s 3000000, about 8 hours after starting the miner
v7.1 win8
I just lost 10 hours by a similar but difference error. The error message is
Restarting thread 0
Sirve/Test ratio:0.0 / 100.0% - New PrimorialMultiplier: 2
then repeat for every other thread. then repeat forever.
Can I avoid the error by turning off the PrimorialMultiplier auto searching?
