Hello,
After my non-published mail I added virtual servers memory from 6GB->12GB and
noted that after 24 hours of letting one switch to run against PF v13 Web UI
reports that total of 11.8GB RAM is used and about 40% of swap is used....
Any idea what's going on there in system? Current top ordered by MEM% included
below... Seems that pfperl-api processes using about 38% of memory and apache
takes around 30%... Is there a way to tune memory usage or is there problems
there in current version of PF?

Aihe: PF memory usage causes high CPU utilization...
Hello,
After debugging my previous problem where Radius seemed to not send proper
attributes to switch I noticed that problem was more in server where cpu usage
was >100 and memory & swap had 100% full (For reason unknown this morning
system worked well with full swap too... Except now after 10mins of use and
raddebug I got another meltdown)
After rebooting PF server everything works really fine for about half a day but
bit by bit swap space is filling up and when swap is full cpu utilization
explodes from "normal" (1min avg around 0.8->2) to 100-200 which causes total
freeze in Radius and of corse webUI too.
Any idea is this some kind of bug if PF, compatibility issue while using
VirtualBox or 6GB of ram for one switch having one port to test mac auth is
just not enough and 16GB is really needed?
My test system is running on AMD Rhyzen 7 having 8 cores/16 threads and 16G of
physical memory. PF 13.0 is installed to Centos 8 Stream which is installed to
VirtualBox instance allocating 6 cpu cores and 6GB of ram to PF...
