Within 2h 30min(VDR's last uptime) the poll timeout occurred 131 times. 
So the average occurrence is less than once a minute. It only happened 
once, that there were two log entries with the same system time. Between 
all the other logs are 3 seconds to a few minutes. Sometimes the 
timeouts occur in "pairs". Meaning, there are only a few seconds between 
two log entries. The then following message is usually ~20 seconds to a 
few minutes later.

I guess I'm fine here since the system seems to be running flawlessly,
