I have no clear answer to you, but generally speaking, no such behaviour
has been reported elsewhere - so I'd claim it's "something local".
Could a stateful firewall (or stupid carrier-grade NAT) be involved?
If you tcpdump on the server side, do you see anything at all when the
connection breaks down and you try to ping through the VPN, like "the
client's ip/port jumping to new values"?
I spent a few hours in a bus recently where the shitty 3G uplink lost
its session state every time we drove through a tunnel (this is really
the worst: no IPv6, and shitty IPv4 NAT), so all my SSH sessions died.
OpenVPN "tls float" to the rescue... needs git master on the server
and 2.3.6 (better: 2.3.7) on the client.
