Hello,

I'm afraid I have chosen the wrong subject. After some testing, I foundthat all tcp connections go in the TIME_WAIT state. This applies toinbound connections and outbound connections. To me it looked like anattack. But now I think it is a kernel error.

After restarting the server a few weeks is stable. Any event brings theserver then to leave all tcp connections in the TIME_WAIT state.



Regards
Uwe
