If this is your first experience of SSL with Apache, you might want to read the onlamp tutorial and commentary.

The messages suggest that Apache is unable to connect to an SSL process.  This is probably obvious, but OpenSSL (or an equivalent SSL package) must be installed, and properly configured, and running, for Apache to operate with SSL.

Personal commentary:  I found Apache support for SSL difficult, especially the all-or-none requirement for virtual hosts.  If SSL is not absolutely required, e.g. for secure transaction processing, I'd skip it.

Using SSL for anything on the modern internet is almost becoming a requirement.
(See also the Letsencrypt project for arguments).

Are you realle bound to apache? Or was it chosen to go with the flow? There are other http servers out there that are more then capable to serve out data like lighttpd and nginx. Those are considerable easier to configure and will turn out to be less resource hungry than apache.

That said, the error seems to point to a client aborting the handshake, so there might be clients that refuse to accept SSL3 offers..., and are you offering TLS1.* (since about a year the advised minimal set, and in some browsers since a year required as minimal level).
