Harry,

It looks like both air and sunny.atmos are having connection problems
according to the LDM logs on thelma;

and there seems to be a periodicity to the failures on sunny and to a
lesser degree on air.

I've looked around a bit on air and don't find anything obvious.  The SE
Toolkit usually shows a moderate or severe lack of memory on the system,
but otherwise OK.  I have a question about the network interfaces and the
split between 89, 175 and 176 subnets.  Is this for load balancing like
DNS round-robin, or to keep LDM or lab data off of a departmental network?

I'm going to look at why ~40 minutes after the hour is a point at which
a fair number of connection issues occur.
