FGT81E - stop logging after few days

Hi guys,

we have installed the new FortiGate 81E and version 6.0.2. It happens to us that after a few days of operation the box stops writing all logs to the internal HDD. Logging into FortiCloud works fine. It only helps to restart the box.

Some ideas?

Thank you.
