I have 5 gridseeds running on a raspberry running cpuminer, after about 10-15 min I get an error and it shuts down.
Here is a copy of what the error says:

Anyone have a bright ideas to fix this?

I had read about name and devcoin and thought they were interesting and the secondary DNS system could be useful in the future with the way some government types think the internet should be tapped in every way possible to prevent bad guy of the day to operate unrestricted, don't worry about all the info we collect on you, if you're not bad guy of the day you have nothing to hide.

I'm rather new only having about 3 weeks of experience, I looked over many different pools and I liked the idea of the merged mining. I think I would like to see a few more coins added if they can be, I know many out there are worthless, but then a few years ago bitcoin wasn't worth the paper it was printed on either.

Is this round taking so long due to an increase in difficulty or just bad luck?
