[Openswan Users] Intermitent Connection

[Pablo García]

Hi, I'm a newbie about IPSEC tunnels, I created a tunel between a Linux
2.6.16.20 on a Fedora Core 5, and a PIX Firewall 535 running soft ver 6.1,
using psk as a method of authentication.
The tunnel seems to work fine, but I have intermitent reconnections and
that's affecting my users, I'm getting this errors in the /var/log/secure
