[volunteergrid2-l] Misconfigured node

[Aaron Drew]

Hi list,

Our debug messages could do with a bit more info like the node that the
error occurred on. I can't seem to find the node name here but someone with
a mac and their tahoe directory built in /Volumes/inari4vms/dkzm has a
broken node! Is that you?

Also, looks like we have less stable nodes than we had hoped. Should I be
lowering my number of pieces or are the people with broken nodes on this
list and looking into fixing their setups?
