Have not been able to reproduce the problem with my small code (may
take 2-3 more days for curl) but here is what I got from
CURLOPT_VERBOSE from that proprietary software run

Accept: */*

If you look you will see a connection is being after every
approximately 30 seconds but in last paragrapgh of output, after that
last line of Host: 192.168.0.230 Accept: */* it hangs on there
forever, it never makes any connection again. Thats the problem.
