Excessive DynDNSUpdaterService activity?

Question

Hello,

I've been trying to diagnose a slow machine, and I was looking at the output of fs_usage for clues. One thing I noticed was that DynDNSUpdaterService was very active. I'm running Dyn Update 3.0 (latest version) on the latest version of Lion. See the output of this command

sudo fs_usage -wf filesys | grep DynDNSUpdaterSer

below. Notice that every second it opens the file /usr/local/dyndns/Config/internet_guide, reads it, and closes it. Is that normal behavior? Is there some setting which I can tweak to check this file less frequently?

Thanks,

Russ

Unfortunately this is a user to user forum, we can't help with Dyn's software.

Do you have any paid services? If so you can report it directly to Dyn (see the Contacts link below). If you don't then you may want to look to an alternative client that works.
