I have a strange problem with a newly configured Linksys RVS4000 that supports 3 tunnels, 2 of which are going to other Linksys gateways and one going to Pix 501. It seems that after a day or so the Pix tunnel drops while other tunnels sre fine. The Pix tunnel is unable to reconnect until tunnel settings are resaved in the Linksys admin panel, the tunnel than comes back up fine.
Here's a log:
