TBS Stop Streaming Until Restart

Hi, i use about 4 TBS2603 to stream to wowza remote server. Service works for 1,2 or 3 days without any problem, then i stop to show video.
The only thing to do is to "restart" manually TBS2603.
I suppose some issues :
1) Tbs 2603 Issue
2) Network issue between tbs and wowza server
3) Remote wowza issue
I can't understand because TBS2603 does not have any log, alert, message log to view what is appening .
Is there a strategy to show some like system logs or system trace to show what TBS2603 is doing ???
I'm using firmware 1.085 (latest of course)
Thanks
