[Openswan Users] DPD

Has anyone ever noticed this particular oddity with DPD? I suspect the method I use to build openswan for smoothwall express 3.1, but I ask in case it is known to happen. (And I didn't build SWE3.0 (openswan 2.6.33) where I've seen it happen as well.

I've noticed that openswan (right now three VMs running 2.6.33, 2.6.48 and 2.6.48, all using klips) brings up the tunnel, then in 8-10sec one of them issues a DPD; this effectively tears down the tunnel and brings it right back up. 2.6.33 and 2.6.48 seem to do this only once. Both seem to do it repeatedly, and I saw 2.6.42 do it repeatedly, too.

Previous testing showed that specifying DPD params in the config didn't prevent this.

Would incorrect build cause this?
