#That certainly sounds like a (libcurl) bug. What libcurl version are you
using
#on what platform? Have you tried to use wireshark to see what's actually
#happens on the network at that point in time? Or perhaps try using
#CURLOPT_DEBUGFUNCTION to get to see more details exactly what libcurl does
and
#what it sends and receives. Could provide some additional clues.

#Does the problem repeat itself every time against the same URL or does it
#vary?

I am using older version of libcurl 7.19.0
I have not tried wireshark yet. You had suggested this in my earlier
questions. My apologies for underestimating wireshark :)...
I will reply in this same thread once I have more data after analysis using
wireshark,

Thanks a lot..
