VPN not correctly disconnected

Hello

Since I have Lion installed on my Laptop I had a problem with the disconnect of an vpn-Tunnel. After Updating to Mountain Lion it remains.

On my MacBook are about 30 VPN Connections in the Preferences basic on the Builtin VPN-Tool of Apple. Both PPTP & L2TP.

The Connections works OK, I used at 10 times a day one of these Connections. Randomly at a discounted it goes wrong. The Connection will be disconnetc but the Menu still displays the text (Connection ABCD disconnected) but it stays grey instead of black. I am not able to reconnect again.

I am able to connect to another VPN but as soon as I disconnect it, it is also grey.

The only way to get it work properly is a restart of the mac.

But after X connections it stucks again.

Is it possible to reinstall the VPN Kernel. Or is their another workaround? I don't want to reinstall all this 30 VPN connections manualy

The Install of 10.8 was a virgin one. I first installed a clean 10.8 with combo update and then migrates the user & programs from my backup

Here is the Console Log when I disconnect for the 2 connections that give a problem this morning

Any Hints?

Regards

Gérard
