It can hardly be the CVE-2009-3555 renegotiation problem.
Both machines have OpenSSL 1.0.0, and RFC 5746 was implemented in 0.9.8m.
It certainly *sounds* like that problem though. Maybe RedHat carried along the broken fix? It would surprise me, but given that it's openssl, not hugely much so :)
It would be worth trying with ssl_renegotiation=0 to see if the problem goes away.
But I'll try to test if normal connections have the problem too.
That would be a useful datapoint. All settings around this *should* happen at a lower layer than the difference between a replication connection and a regular one, but it would be good to confir mit.
