Peter, This is documented in the readme.txt file. One round off error is possible. If you get it again at the same place or you get it often you have a problem : it could mean your computer is overheating (dust accumulation f.i.), you installed a bad driver or other bad software recently...
You cann consult the mersenne forum http://www.mersenneforum.org/ for more info.
