Fortigate 60E - 6.4.4 - high gradation of memory without deallocation

Hey guys,

I would like to know if anyone has had difficulty with the 60E model in version 6.4.3, 6.4.4 and 6.4.5 high gradation of memory without deallocation, I could not identify high consumption of any process such as IPSMONITOR, IPSHELPER, IPSENGINE, WAD or any other another process.

I already opened a ticket with the tac but so far there has not been an effective answer about what the problem is, I decided to format some equipment but some of them again presented a problem with high memory consumption, all the equipment is clustered and the problem reserving the memory occurs on any equipment on the master or slave the increase is gradual but there is no process reserving the memory.

I appreciate the help.
