Socket / Connection Reuse without fdCloseSession

I have a single Ethernet Client task started by the TCP/IP initialization callback that opens up a socket every ~15 seconds, sends data to the server, receives data from the server, and closes the socket.

My sequence of commands is:

fdOpenSession 

while(1)

    socket (AF_INET, SOCK_STREAM, IPPROTO_TCP)

    connect

    send

    recv

    shutdown (tried with and without this)

    fdClose

Problem: Every “socket” statement allocates a new 512 byte socket until there is no available heap available.

Do I have to start a task that will fdOpenSession/fdCloseSession for each transaction?

Is there another way to accomplish this task?
