Running HEAD from 2-27-12, tested with MSI disabled and
did not see any problems, this with a network traffic volume comparible to
that when I had the original problem, which was running -current
from 01-20-12.

Then re-enabled MSI and using svn, loaded /usr/src for HEAD
and did not see any problems there either.

This traffic volume was also comparible to the earlier time when
the problem occurred,  running -current from 1-20-12.

It appears the problem may have been solved.
