No, I think for 32. Can you show `perf top` screenshot. What in accel-ppp logs and dmesg? Provide please also `accel-cmd show stat`

Hi @hashbang, I don't know about frr ping command, but I think you can make some things. Try set in section [ppp] param unit-cache=3000 and then execute `accel-cmd reload`
from docs
https://accel-ppp.readthedocs.io/en/lat ... n/ppp.html
unit-cache=n
By default is disabled: unit-cache=0
Specifies number of interfaces to keep in cache. It means that don’t destroy interface after corresponding session is destroyed, instead place it to cache and use it later for new sessions repeatedly. This should reduce kernel-level interface creation/deletion rate lack.

Did you check journalctl and dmesg? What about accel-ppp.log and accel-cmd show stat?

As alternate routing daemon, you can use `bird`, that is an idea to confirm/decline that issue exactly with FRR

Try to set '[radius]acct-timeot=0` and server=.....req-limit=0 in case if rodius does not responding.
Can you also provide your [radius] section?
