At what default memory percentage does FortiGate enter conserve mode?

FortiGate devices enter conserve mode when their memory usage reaches a default threshold of 88%. When the system detects that memory usage has hit this level, it initiates conserve mode to optimize resource allocation and maintain operational stability. This mode helps prevent performance degradation or crashes that could arise from high memory utilization by limiting certain processes and functionalities.

Understanding this threshold is crucial for network administrators as it informs them about the memory management behavior of FortiGate devices. When the device enters conserve mode, it affects various functionalities which could impact the user experience and overall performance of the firewall. Maintaining awareness of the 88% threshold allows administrators to proactively manage resources and perform necessary optimizations before the device needs to resort to conserving memory.
