TCP errors ?

Hello,

I'm getting a lot of messages like this, what is that supposed to come 
from ?
No harm done AFAIK but my dmesg gets bloated ?

    TCP: [192.168.0.100]:389 to [192.168.0.100]:53612 tcpflags
    0x18<PUSH,ACK>; tcp_do_segment: FIN_WAIT_2: Received data after
    socket was closed, sending RST and removing tcpcb


Thanks in advance.

Bruno
