Fortgate 80E firewall memory usage hanged up at 82% and Firewall Showing (Conserved mode Error). Which stopped firewall mode to 82% usage for safer side.

Some services were working and some were disturbed. I deleted all logs of fortigate to resolve this issue. 

 

Needs suggestion from Senior members what was this issue, why this occured , what is best approach to reolve this issue? Either my solution was true or not?
