MOTP stops after few hours

[SoRRoW]

Right set Freeradius2 with MOTP, both client DroidOTP and Swiss SafeLab working like a charm, but after few hours the authentications stops to work. Epoch time is correct.

Then, a simple click at the save button at freeradius settings or at user config without change anything bring authentication back to life.

Any ideas?

Not 100% confirmed yet, but looks like after change the log location for FreeRadius from system to radius.log the issue stops.
