Queue Log stopped working

Hello,
I notice that all (5) of my FreePBX stopped to login informations in queue_log, aprox. since end of january.
Have anyone faced the same issue?

It seems that after a logger rotate it adds the following:
1457039116|NONE|NONE|NONE|CONFIGRELOAD|
1457039118|NONE|NONE|NONE|CONFIGRELOAD|

But that is it, no real queue informations.
