On one of our 5510 ASA we have approx 90 VPN site to site tunnels. The site ends terminates to Sonicwall devices. We are having issues with 2 tunnels that work and then for no reason data stops, as if the tunnel has dropped, but the monitor on the ASA shows as still connected. Once the tunnel is reset on the ASA the tunnel comes up and works normally.
The settings for both these tunnels are identical to every other one. This issue may happen once or twice a day and then not happen for several days.
