    <p>Hello,</p>
    <p>you were looking at the wrong log message, that warning is not
      the reason of kamailio not running, just saying that libssl is
      known to have some issue when low shared memory is available, but
      starting and operating is fine till that moment.</p>
    <p>The real problem is pointed by:</p>
    <p>Sep 03 12:09:18 talk /usr/local/sbin/kamailio[27270]: ERROR:
      <core> [core/tcp_main.c:2850]: tcp_init(): bind(c,
      0x7f0b41b001f4, 16) on <a href="http://172.31.35.49:5091"
        target="_blank">172.31.35.49:5091</a> : Address already in use</p>
    <p>There is another application listening on the same ip:port. Maybe
      kamailio is already running?</p>
    <p>Cheers,<br>
      Daniel<br>
