Execute connect_ssl() twice to connect - is this right?

Hi all,

I would like to verify some behavior that I observe in my code when I
connect a client and server using M2Crypto. I am finding that I have to
execute the connect_ssl() method twice in order for a connection to be made
between the client and server. Is this right or am I doing something wrong?
Thanks for any information that anyone can give me.
