Murph77 Posted February 8, 2016 Share Posted February 8, 2016 Last night I noticed my CPU utilization was at 98%, which is rare and seems unrelated to what I am presenting here, so I pulled up my logs. It looks like for the past day or so I have the entries below. They started at a low port number and are counting up on every entry. Shutting down my VM's and Containers makes no difference nor does rebooting the whole system. Any ideas out there?

danioj Posted February 8, 2016 Share Posted February 8, 2016 The only thing I can find on the forums is this thread: http://lime-technology.com/forum/index.php?topic=29841.0 In summary denzo suggests that: The message appears to be an announcement rather than an actual response to a query. In section 8.3 (Announcing) I found this paragraph: "A Multicast DNS Responder MUST NOT send announcements in the absence of information that its network connectivity may have changed in some relevant way. In particular, a Multicast DNS Responder MUST NOT send regular periodic announcements as a matter of course?." So the "fix" was a firmware upgrade to the router After some quick Googling it also appears that this LT post was referenced from Launchpad as a possible solution to a similar / same error: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/447442 Disclaimer: No idea really. Never seen the error before. Just trying to add some help! Quote Link to comment
