Who kills accel-ppp? Check please journalctl. Maybe systemd or ...

Ah, ok.
You need to check `ps ax | grep accel` first.
Show me `dmesg -T` and `journalctl` 2020-05-18 from 17:00 to 18:30

Hi,
It seems like when there is a flapping in some part of network.
accel is unable to handle so many request
After sometimes it restarts by itself so creating a mess in itself and radius (increased number of start sessions )
if it recovers then interim update stops
else systemctl shutdown accel-ppp wait for some seconds
start the services.
this is my deduction
thanks

Hi @hashbang, please set up your firewall at first. I see in your log a very odd situation.

Code: Select all

May 23 15:49:41 hbbras00 polkitd[2088]: Registered Authentication Agent for unix-process:7851:122129258 (system bus name :1.5085 [/usr/bin/pkttyagent --notify-fd 5 --fallback], object path /org/freedesktop/PolicyKit1/AuthenticationAgent, locale en_IN)
May 23 15:49:41 hbbras00 systemd[1]: Stopping Accel-PPP...
Note; In your `dmesg` output I don't see accel-ppp core dump information, which means accel-ppp daemon finish with normal code (not segfault).
I segfault case, I will recommend to build accel-ppp with additional DEBUG flags and run in GDB https://accel-ppp.readthedocs.io/en/lat ... index.html
