[Openvpn-users] new beta15 keeps restarting

[Kurt <kurt.semba@xxxxxx>]

Hi,

I had beta11 running quite stable for a while. I updated server and all client
to the new beta15 release and get the following problem:

After a (not yet defined, but mostly round about an hour) period of time the
server seems to get a system signal to restart itself. While trying this the
server crashes when it wants to open the tun interface....sinc it is still open
from the former process, I guess.

hier the logs (verb 6)

In my opinion it is the "Interrupted system call" at the beginning that causes
this restart. But why should the server want to restart? What application could
cause this restart? Or could it be that there is somethins wrong with my
iptables fw settings I use? Any ideas would be appreciated :)

Thx,
Kurt
