Has anyone else seen this? It looks like a bug, and I have a support case open #1538773. The unit stopped checking in to our N-Command system and throwing CLI errors like:
2013.09.05 16:00:02 HTTP_CLIENT Could not resolve hostname auburn.impulse.net
The unit had no hosts in its hosts table.

Configured no ipv6 unicast-routing and that didn't fix it. I will reboot the box tonight after hours to see if that fixes it.
A reboot seems to have fixed it. Also re-uploaded the firmware in case previous version had an unknown issue. Will continue to watch this.
This continues to be an issue. RQST00001538773 opened in September, still not fixed.
Just got word that this is fixed in R10.5.4 out soon as well as R10.9.2.
