Problem fixed. I'm not sure how it happened but I guess when I upgraded from 2.2.6 to 2.3 Alpha a IPsec tunnel that I had disabled was re-enabled and since I didn't have the other end configured the tunnel didn't come up. I guess IPsec tunnels take precedence over OpenVPN tunnels even if the route is not available.
New snapshots including that fix are out, please try and report back.
On my "spot", i got about 120 simultaneous connections and it's working fine. I think it's solved, but could someone with big numbers give us more reports ?
Thanks for pointing that out. I completely missed that.
Will try when i get home, but its very likely ive scp'd into the wrong dir at one point over the last couple of days while debugging a different issue.
