- Status changed from New to Rejected
- Priority changed from High to Normal
- Target version deleted (
2.5.0)
There isn't nearly enough information here to qualify this as a bug. Keep the discussion on the forum for now.

I just ran into the same thing on one out of 3 lab machines.
Each one announces one /44 or /48, receives default route only and has about the same specs. Usual load very low. Load now 1.50 - 2.50, using more than 1GB of RAM and swapping out, web GUI timing out.
The only thing different on the instance that is locked up now is that it is on a different hypervisor. It is on VMware ESxi with VMware tools packages installed. I will try reach out to the original reporter to compare notes and see if we can come up with something tangible.

i have no install vmware, I installed the pfsense 2.5 system on the hardware server. AMD CPU and DDR3 16G RAM.SSD DISK
just i am running frr bgp, get a lot of full route tables from some upstream. Because I have many different locations and different servers upstream.
ihave tested frr use the "service integrated-vtysh-config" run in ubuntu system. This mode also takes up a lot of memory and resources. if deleted the "service integrated-vtysh-config" Will reduce the use of memory resources by at least twice
When FRR is stopped, resources will be relieved

when you try receives a lot of full routes,For example, millions and tens of millions of routes, You will see that the CPU is full,The entire pfsense webgui is locked.

Turns out my issue was unrelated. My issue was https://redmine.pfsense.org/issues/11404
My instance was accepting more routes than what can fit in its RAM and things started falling over.
