We have since done 1000 tunnel tests using both Openswan and Freeswan
without problems,  but we haven't ventured any further.

Call it closed if you like,  we will eventually get around to pushing
the tunnel limits again,  but it's not a priority right now so I cannot
put a timeframe on it.

It definately wasn't the OOM killer,  the systems pretty much hose
themselves completely whenever that kicks in ;-)

Cheers,
