OpenVPN general issues

Hi

I have some openvpn issue of my own I was hoping to get some help with.
ROS 6.13
Hardware: RB2011UiAS-RM

I’m running an OpenVPN server on the Mikrotik device. All client sessions get killed at 61 minutes - the logs all look as follows:

May/31/2014 13:35:54 : connected
May/31/2014 14:36:54 : terminating… - internal error

Always 61 minutes, without fail and across Windows, Linux and iOS clients. Any ideas?

Further, we are seeing generally awful performance with the OpenVPN sessions - packet loss and dropouts are frequent. Most of the clients are about 150ms from the router, with good connection and minimal packet loss outside of the OpenVPN tunnel. CPU is barely utilised so not sure what’s going on here. CAn provide whatever config you need to troubleshooot.


thanks
