[SR-Users] Kamailio suddenly stops

[Javier Valencia]

Hi there!

When I start my webrtc kamailio suddenly stops.

I can see this on syslog:

SSL info:

    root at webrtc:/etc/kamailio# apt show openssl

    Description: juego de herramientas Secure Sockets Layer - utilidad
    criptográfica
      Este paquete forma parte de la implementación del proyecto OpenSSL
    de los
      protocolos criptográficos SSL y TLS para la comunicación segura a
    través de
      Internet.
      .
      Contiene el binario de propósito general para la línea de órdenes
      /usr/bin/openssl,
      útil para operaciones criptográficas como:
       * creación de parámetros clave RSA, DH y DSA;
       * creación de certificados X.509, CSR y CRL;
       * calcular resúmenes de mensajes;
       * cifrado y descifrado con cifras;
       * probar clientes y servidores SSL/TLS;
       * gestión de correo firmado o cifrado S/MIME.

Should I use another version of openssl, or maybe use gnutls?

Regards,

Javier Valencia
