Cisco VPN Drop

I have a site to site VPN between an ASA5520 and a PIX515E.

Recently, this VPN has started to drop. This is seemingly at random intervals, but it is always during the evening/night - never during the working day.

The tunnel drops for anywhere between 15-40 minutes before coming back up again with no config changes having been made.

While the VPN is down I am still able to access both the ASA and the PIX using the remote VPN client, as well as non-vpn accessible resources (i.e. websites) behind both devices.

I have some syslog captures from both ends during the issue. The entries specific to the VPN are detailed in the attached file (the trap logging is set to Error). VPN-Issue.txt

It could be a connection issue between two sites. xx.xx.xx.34 didn't respond for 90 seconds to ASA's query packets and ASA assumed the other side is inactive and tore down the connection. Try to run a continuous ping and see if there are any packet losses.

I'm not sure why it would have made a difference, but we had some L2L VPN configs still in place for sites that were no longer connected.

I did a clean-up to remove the configs for all VPNs no longer in use and we haven't had the problem happen again since.
