    not really, in a stream protocol, such delays can appear due to
    congestions in some routers -- the apps just have to keep reading
    until a format error, packet is complete or connection is closed.
    Few seconds could be very common in between parts of large sip
    messages.<br>
    <br>
    Are these sequential CRLFs causing problems?<br>

              is kamailio sending crlf after the second crlf from the
              client?<br>
              <br>
              There is no notion of a packet in a stream connection,
              even a sip packet can be send char by char and the server
              has to assemble it by keep reading in a local buffer until
              all is retrieved.<br>

                          looking at the code, it seems that CRLF is
                          sent only after CRLFCRLF. Can you get a pcap
                          for your case?<br>

                                    description, kamailio shall reply
                                    CRLF only when it receives &quot;CRLF
                                    CRLF&quot;.  But In the 3.1.0 version, if
                                    kamailio recieves &quot;CRLF&quot;, it respond
                                    back CRLF.  Is this an expected
