FGT not loggin UTM events

[DemetrioMello]

Hello ladies and gentlemen; My Fortigate has stopped to log UTM events. It' s normally loggin the traffic, but since yesterday it' s not loggin UTM Security Logs; I have checked all firewall policies and it' s normally LOG ALL SESSION in Log Options. As I said before, It was loggin normally until today. And... yes, the UTM Sec Profiles are enabled and selected for all the firewall user groups; Box: Fortigate 200B v5.0,build0179 (GA Patch 2)
