The connection aborted during the SSL handshake for some reason,
winsock send() returned -1 (SOCKET_ERROR):

I've no idea why, it doesn't look like the client application closed it.
Did you enabled all options in the TIcsLogger?

I'm running out of ideas.

If so, there should be an entry in the event log AFAIK:
"EventID 4226: TCP/IP has reached the security limit imposed on the
number of concurrent TCP connect attempts"
This limit applies to halve open connections rather than the number
of connections.
