After re-booting the master or slave of my cluster of 2 ASG v8.160 on an ESXi 4.1.0 (build 348481) I'm getting
2011:03:09-15:10:25 asgtest-1 ha_daemon[5957]: id="38A0" severity="info" sys="System" sub="ha" name="Access granted to remote node 2!"
2011:03:09-15:11:25 asgtest-1 ha_daemon[5957]: id="38A0" severity="info" sys="System" sub="ha" name="Notification from 2: MTU error on HA interface! Shutting down in five minutes..."
and the restarted ASG goes down.
The setup is quite simple: 3 interfaces (intern, extern, HA), initial license, nothing special. Bringing up the second node via 'Automatic Configuration' worked fine but restarting one of the nodes after that ended up in the described error.
Just one note: This setup on my ESXi works fine with the current stable version 8.102...
