Hi,

I'm runnnig rsyncd on an i386 with Jun 19 -current.
Once I lanuch rsync client from another host running
6.2-STABLE, I saw lots of

TCP: [192.168.30.48]:64597 to [192.168.30.69]:873 tcpflags 0x4<RST>;
tcp_input: Listen socket: Spurious RST, segment rejected
TCP: [192.168.30.48]:64597 to [192.168.30.69]:873 tcpflags 0x4<RST>;
tcp_input: Listen socket: Spurious RST, segment rejected

and the rsync client stops with various error messages.
It's really annoying. Any ideas?
