Do you have tcp_syncookies on?

syncookies = 0.

And are you exceeding the len as configured by tcp_max_syn_backlog?

max_syn_backlog = 256.

My server program sets its backlog to one and pauses ninety seconds before
accepting connections.  Within that ninety second interval, I start three
client programs that do an active open to my server.  I expect one of
connections to get discarded when the server's connection backlog limit is
exceeded.
