false tcp connection

Why this happens?
How to solve this?
Code:
$netstat -na |grep 9325
tcp        0      0 127.0.0.1:9325              127.0.0.1:9325              ESTABLISHED

When a client socket repeatedly tries to connect to an inactive(no server socket is listening on this port) local port,connect succeeds.

System Information
Code:
$uname -a
Linux pztest.locadomain 2.6.18-92.el5 #1 SMP Tue Apr 29 13:16:15 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux

So it's a connection from localhost to localhost ??
The only time I've seen port 9325 beeing malicius is as UDP port, where the Mstream trojan uses it.

Problems would arrise when it was a listening port (netstat -ln)
