Have had several batches of patches pushed through yum auto update, but nothing concerning NM to fix this problem. I set PEERDNS=no with no affect. I set /etc/resolv.conf to a workable solution and then removed the write bits and set it immutable. I get errors in /var/log/messages about it, but the behavior is still the same. After a reboot, all is OK. After a while, dns dies. Restarting NM brings it back to life...then it dies a few minutes later. As long as someone is actively accessing the net, dns seems to stay up. But give it a few minutes of idle time and something causes it to stop. Here is a snapshot of /var/log/messages before, during, and after a NM restart. Can anyone figure out what is going wrong with dns? Feb 2 21:23:45 desk NetworkManager: <WARN> nm_signal_handler(): Caught signal 15, shutting down normally.
