Failed connection with TV after a few minutes

Hello,
Each time I start Serviio server, everything runs well : I can browse my movie library, I can launch a movie...
But after a few minutes (even with no activity with Serviio), if I browse my library again or i want to launch a new movie, it does not work, meaning that my library is not accessible from my TV anymore.
On Serviio console, my TV is not recognized as a Sony TV anymore but as an unrecognized device. Aand a new device has been added with IP address 192.168.27.14 (always the same) and the correct profile (Sony Bravia TV 2011)
I have tried with 0.6x, 1.01 and 1.1: I have got the same problem.
Thanks for your help
Here is my config:
- TV: Sony 40ex721 with the lastest update
(connected by wifi or hardwired through a router: in both cases, I have got the problem)
- Serviio (now 1.1) running on a PC with Windows 7 64-bits Ultimate
- Local network: fixed IP address on every item
I have attached a Log file and 2 screen copies of Serviio console when it works and after the problem appears.
