I'm having an intermittant problem with my internet connection dropping every ten minutes or so and have actually found it is happening at the same time as two dnscache processes appear on my SME 7.1 box.
I've read on these forums that this could be related to relays.ordb.org shutting down. I have found that actually sending an http request or ping to this host invokes the dnscache processes and eventually kills my adsl connection.
I'm guessing that the volume of requests generated by the dnscache processes is killing my router and initiating a reboot.
I have tried a few of the things mentioned ala removing relays.ordb.org from my setup, but this doesn't appear to do anything.. Has anyone come up with a workaround for this?
