We have several RV082s here which are intended to connect to a central ASA5510 firewall. The VPNs are configured and do work basically, however in our test environment the RV082s kept crashing after an apparently unpredictable amount of time (sometimes after several days or even weeks). All the RV082 have the newest firmware installed (v4.1.0.02-tm).

When further investigating the issue, I found out that the crashes can be reproduced when enabling the keep-alive option on the RV082. When powering up the RV082, they boot, start up the VPN, and then they crash a few seconds after the tunnel has been established (one or two pings usually get through). When crashing, the RV082 becomes completely unreachable, ie no ping, no webinterface etc.
There is a note in the firmware release notes saying that enabling the keep-alive option would not work the way it should. However it seems that enabling that option lets the router completely crash after its next reboot. This makes the keep-alive option basically worthless, however we need this since the routers will get installed at remote sites with no personnel available there.
Is there any way to enable the keep-alive option without making the routers crash immediately after startup?
