The Gmail servers are probably simply dropping the connection without politely closing out the TLS protocol. When OpenSSL tries to end the connection using the TLS protocol, it receives an end-of-file message instead. Since the email message has already been accepted, it's really not a problem. You're only seeing these errors because the spamdyke log-level option is set to "verbose" or higher. If you turn it down to "info" or lower, they'll be suppressed.
