System time lag causing inactivity timeouts

Damien

Hi everyone,

I'm sorry to bother you all with this, but I have really been losing my mind over this, unable to find a solution. I'm using OpenVPN on my Virtual Machines (2), but unfortunately I keep getting "inactivity timeouts" after my system's time sync!?

Logs from one of these instances:

VM1:

Sun Sep 27 09:50:44 2015 [server] Inactivity timeout (--ping-restart), restarting
Sun Sep 27 09:50:44 2015 SIGUSR1[soft,ping-restart] received, process restarting
...

VM2:

Sun Sep 27 09:50:42 2015 [server] Inactivity timeout (--ping-restart), restarting
Sun Sep 27 09:50:42 2015 SIGUSR1[soft,ping-restart] received, process restarting
...

After some investigating I found out that these "inactivity timeouts" are ALWAYS preceded by this event (as noted in my main system's "Event Viewer"):

27.9.2015 9:49:05 Kernel-General (The system time has changed to ?2015?-?09?-?27T07:49:05.500000000Z from ?2015?-?09?-?27T07:47:55.593948500Z.)

This keeps happening every 6 hours or so, during which time my system time lags for around 1 minute.
I managed to confirm this by manually synchronizing my system's time - again "inactivity timeout" followed.

Any suggestions/solutions?

Thanks!
Regards,
Damien

what hypervisor do you use?
how do you sync time?

VMware Workstation 11.

You mean how I manually tested it? Just by going to taskbar's clock and clicking "Update now" on "Internet Time" tab, thus synchronizing it. "Inactivity timeout" followed immediately. This is just how I managed to confirm that every time the system corrects time, "inactivity timeout" follows.

How can I prevent this? I don't care about correct time, I just want to prevent inactivity timeouts.

did you installed vmware tools in your vm?

Yes, of course.
