Openvpn server: Linux
OpenVPN client 2.2.1 as service: Windows 7 Professional
Every time clients want to reconnect server log returns

I’m sure there is no other clients use the same certyficate or common name.
I don’t want to enable duplicate-cn option on server.
It looks like every time old session is not closing before the new request is comming.
Should I worry about this log messages? My clients are unstable with connecting and I’m looking for solution.
Sometimes pings to server are fine but sometimes after 3-10 pings client disconnected. After OpenVPN restart, 3-5 pings are OK and again disconnected.
Another time everything works fine and stable.
