Hi Daryl,

A couple of quick comments:

- Mike found that a site in Brazil was trying to connect to iddb
  every 5 seconds, and this was causing a myriad of problems

  The site's IP address (there is no reverse DNS for their IP), has
  been blocked, and things have quieted down a bit.

  Time will tell if this was a cause/the root cause of the latency
  problems on connections to iddb.  It does not, of course, have
  anything to do with high latencies on idd.

- several years ago (3, 4, more?  I can't remember) we had a problem
  with connections from a downstream piling up when old connections
  were not seen by the upstream machine to be gone

  I remember that the problem was eventually traced back to a firewall
  setting on the upstream machine, but exactly what needed to be tweaked
  is not coming to mind right now.  I will be "talking" to Mike to see
  if he remembers exactly what we needed to do.

  Also, this situation was what led to the implementation of DOS capability
  in the LDM

Again, just a couple of quick FYIs...

Cheers,

Tom
