HW errors with bfgminer proxy and asic blades

[brudog]

   I've got two blades running on bfgminer 3.4.0 proxy with a batch file and one blade will get lots more hardware errors than the other. I can restart the proxy and the errors may switch to the other blade. I created a batch file with : bfgminer --http-port 8332 -o pool -u user -p pass . Is there a better way to write the proxy? one blade will be at .48 HW errors and the other at 6.0 or more.
