When I run profiler, I noticed that libCURL is invoking poll method
which is quite surprising to me, because I am using epoll to poll the
sockets and I did not expect this call. Then I saw a comment in source
code that
                    /* Call for select()/poll() only, if
read/write/error status is not known. */

May I know the reason for the failures? What I shoud I check here?

Next, I see some considerable amount of time being spent in
Curl_send_plain (to send request to server) and Curl_recv_plain (receive
response) calls. Is this again because of above error?
 
Please suggest.
