Firepower Management Center - very high CPU usage

[fabian.seeber]

hello team,

i want to use the FMC with Firepower. Now i tested the system with only 1 firepower module (hardware) and i always have a CPU usage with an average of 80%. It's so high, that my system is to slow to handle it. The Software of the FMC and firepower is all actual and updated.

The FMC has its own server. ESXI, 8core CPU, 32GB RAM and 500GB HD. So i doubled the hardware that you need to handle it. no effect!

I added 2 pictures from the usage.

Please help me. Dont know what can help now. Thats only one module and i want to use maybe 5 in the future with the same FMC.

best regards, Fabian

You cannot free memory from cli practically speaking.

The FMC can reload without affecting connections through the managed devices. So if it's a VM, you can shutdown the FMC, increase the allocated memory and then restart it.

We tested another server now with 3 times more power than the other one... now it works good. it has 9% average cpu usage and it's possible to work with the system.

thanks a lot for your help and time :-)
