Hi,

Just increase log level and set verbose for all modules, I think we can found the answer on accel-ppp detailed logs.
NOTE: Please, configure your firewall

hi,
accel-ppp service restarted mysteriously.
Jun 06 00:15:10 hbbras01-153204 systemd[1]: accel-ppp.service: main process exited, code=killed, status=9/KILL

debug file is too big so extracting will take time. Above has been taken from message.
some nms graphs may reveal something @11:10* active users went down and after one hour a service restart

Hi, can you run accel-pppd process in GDB?

Hi,
It has been confirmed that whenever there is a big network flap affecting 1k+ users, accel-ppp service restarts which aggravates the problem relogin so many users at once. I'm awaiting for new h/w to get debugging into gdb done.

thanks

again network flapped same situation but this time accel-ppp service started every few minutes. I found after 10 minutes as my interim update is 10min. Restarted accel-ppp many times but problem didnt resolved. Rebooted the server then things went fine.

thanks and regards

Hi, you can also try to add to [common] section parameter max-starting.

Code: Select all

max-starting=n
By default is disabled max-starting=0

Specifies maximum concurrent session attempts which server may processed.
But will be better to get coredump and capture logs
