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...
