By connection establishment I assume you mean amqp_socket_open() on a
socket you create with amqp_ssl_socket_new() ? The timeout for opening a
TCP/IP socket to the broker is dependent on your operating-system (you'd
need to look at the documentation for what the timeout is for opening a
tcp/ip socket). The OpenSSL layer operates on top of this TCP/IP socket,
and a certain amount of reading and writing to the socket must occur after
the socket is opened for the TLS socket is considered open - each of these
operations has a timeout associated with it.

Short answer: I cannot give you a good answer for this.

Also while amqp_login fail the API return

If the amqp_login() function returns an AMQP_RESPONSE_LIBRARY_EXCEPTION,
this does not mean that a segmentation fault has occurred in the library.
It usually means that some other error has occurred and that you should
check the library_error member of the amqp_rpc_reply_t struct and compare
it against the values in amqp_status_enum to determine what went wrong.
