pmEthernetReadConfig(0x83cdc48, 0, 00:A0:CC:5B:8D:17, cu): node number
"0" conflict
pmEthernetOpenDevice("/var/scored/scoreboard/tb0000B2001cAt",

Heh.  I should have done this before I tried to strace the error.  I
spent 30 minutes following calls into your code and finally decided (aka
guessed) that pmEthernetReadConfig was returning EBUSY which was being
passed all the way up back up the line.  It looks like I may have been
right.

Any ideas from here?
