pix to vpn 3000 von tunnel drops

Can anyone give me some insight as to how I would debug a problem that everyday the tunnel between a pix and vpn3000 keeps dropping. The tunnel does not get used much, but later in the day when it is used the tunnel light is lit up but now traffic seems to pass. A full reboot of the pix seems to clear itup

Would it be possible to run some debugs on the Pix and the VPN3K?

On the Pix

debug crypto ipsec

debug crypto isakmp

On the VPN3K

Navigate to Configuration | System | Events |

Classes

and select the following classes

IKE

IKEDBG

IPSEC

IPSECDBG

at Severities 1-8

The debug information will tell all.
