SVDRP is not implemented as a thread. Processing the SVDRP interface is part
of the VDR main loop. The problem is that if you are uploading EPG fast
enough, the SVDRP code will remain in cSVDRP::Process() until you're done. So
the watchdog timer will not be refreshed and the watchdog eventually fires.

There are two possible workarounds:
1. increase the watchdog timeout
2. take a short break from time to time while uploading the EPG. The "while
(file.Ready(false))" loop in cSVDRP::Process() has a timeout of just 10
milliseconds. With a sleep of 100ms you should be on the safe side, as you
still need to take into account that network traffic is buffered on both, the
client and the server.

Cheers,
Frank
