I'm not sure what it is I've got here. I just tried to restart boinc,
which hadn't run here in 10 days or so, cause its not housebroken yet
IMO, and got this in the shell I started it from after a failed
connection to berkeley attempt, followed by a repeat access:

Can any sense be made from this? This is 48-33 with the two items
mentioned before in this thread disabled.

Cheers, Gene
