Client OS that crashes won't be allowed to reconnect to serv

[stren]

Hi, I'm having a problem with my vpn setup. As I currently can't login until I reboot the server I'll have to wait to post the server configuration.

At work we have an openvpn server running under esxi, it authorizes against the active directory running on win 2008 r2

Essentially if my client OS crashes (or if I do a hard termination of the openvpn process (i.e. kill -9)) I can no longer reconnect to the vpn. Others however can access it just fine. To fix the problem I simply start and stop the server from the web gui, or restart the server itself.

The openvpn server logs show this error, even though there should be plenty of assignable IP's. For example at the time there was only one connected user, and the opevpn setup states that the dynamic IP pool has over 20 IP's available for it.

DEFAULT_USER: IP address pool depleted: internet/defer:181,internet/defer:323,internet/defer:284,internet/defer:280,internet/defer:323,internet/defer:766,internet/defer:746,omi/auth:422,sagent/usersvc:744,sagent/usersvc:903,sagent/usersvc:390,sagent/usersvc:192,sagent/usersvc:151,sagent/usersvc:132,util/error:52,util/error:32 (VPN_AUTH)

My client log just shows:

Are there some settings I can change to fix this?

Thanks in advance!
