Hello Everybody,

finally the problem seems solved. It had something to do with the 
network card. After switching to the other card (onboard r8169), the 
problem seems to be solved.

I still do not believe that it is the Intel PCIe card. It has not given 
any other problem apart from this sporadic situation caused when any 
frontend is idling in the recorded programs screen. I would rather like 
to think that this is due to a misconfiguration or a bug, something that 
does not happen in 0.26, but I will not find out.

Anyway... switching cards did it for me. Switching back brought back the 
problem, after 24 hours or so running the backend. Switching back fixed 
it again.

So I take this as fixed.

Cheers and thanks for the support

Matthias
