High memory utilization.

[ywangchuk]

Our customer is using 100F  firewall with os version of  v7.0.14,build0601,240206 (GA.M).  Recently, we noticed that memory consumption is spiked up to  71.5% of the total memory. Upon checking  the processes, we noticed that fnbamd process is consuming 12.2 % of the total memory. 

What should I  do to solve this issue. 

Your assistance would be greatly appreciated.

Hello @ywangchuk ,

fnbamd service is responsible for the remote authentication(LDAP, RADIUS,FSSO, etc.) process. Did you make any changes related to remote authentication? Do you see anything related to remote authentication in the system logs?

You can review these documents also.

My advice is, if you have a valid contract you can open the case to Fortinet Support. Fortinet engineers will thoroughly examine your device

If you are looking for a quick fix, you may restart the process and check if the memory usage comes down.

Ideally restarting the process is not expected to create any issues, but it is recommended to run these during non peak hours or maintenance windows to handle any unexpected issues (if any comes).

If you have a valid support contract you may open a ticket with our support team as suggested by ozkanaltas to check further before restarting the process.
