OK, so, considering that Fortinet is removing a lot of "proxy" features from entry-level FortiGate devices in versions 7. This unit was added back into cluster as secondary unit. Scope: FortiGate v7. Process Memory Consumption: Review process memory consumption using the command: diag sys top-mem 20; F4 # diag sys top-mem 20. Or the command 'diag sys process pidof' can be used on current firmware releases to list all process IDs of a given process name: diagnose sys process pidof wad Also, conserve mode is often associated with memory leaks, so having more RAM would reduce the frequency of the problem, not eliminate it. All HW test were done, and all passed. 2/6. Only resolution is to kill the service/reboot device.
