Serviio disconnects when "save/Refresh" used

I have a repeatable issue like this. I thought at first it was when I used the Refresh that the server had issues but it appears to be a combination of saving settings and refreshing. If I make a change, save it. Nothing appears to happen. But if I than hit refresh my connection crashes about 3-15 seconds later.

I tried this three with the same results. I've turned on debugging but it doesn't appear to have taken effect. I'll try to get a proper log file uploaded when I figure out how I diddled up the config setting.

(EDIT: I'm running on Windows 7, AMD quad core, 8GB of memory, Wireless Netgear N600, 802.11n/80% strength)

What I did to get the disconnect:
1. Start Serviio
2. Connected via Samsung TV and played a 'last viewed' Paused it for a bit to let my PC settle down from restarting the server.
3. Changed my PC settings to some other device and saved it. Paused about 10 seconds nothing happened.
4. Hit refresh and waited. It took about 15 secons before the TV disconnected. I was just starting to do another save when I got disconnected.

On a prior test I had to do this twice before the TV/Serviio lost connection. After this I have to stop/start Serviio in order for my Samsung TVs to see Serviio again.

Hope that helps.

Steps taken to get Serviio to disconnect:
1. Started server, waiting for system to calm down.
2. Started "Dark shadows 353". Allowed to play for 10-20 seconds.
3. Opened console. Changed my PC from generic DLNA to first optiona and 'saved' config.
Waited 20 seconds, nothing.
4. Hit 'refresh' button and TV disconnected in about 4-6 seconds.

log file attached.

The TV is 192.168.1.70. The 'second nic' is a virtual one that is not in use.

If you change profile, it'll restart the UPnP service, so you would get disconnect.
