I have compiled monero from source and am running a full node under Ubuntu 14.04.3 LTS. The machine hosting the node sits behind a router. The node started OK, and was syncing for a while. Now, the deamon exits every few seconds with these messages showing up in log files:

ad infinitum...Is this a networking issue, or is the UPnP warning irrelvant?
Anyone here that runs a node under Ubuntu, who compiled from source recently?
