What is raclient and what triggers raclient running raclient.sh?

I have an XGS firewall that requires a monthly reboot via the front panel power switch because raclient is spawning multiple sh processes per second that become zombies until SFOS runs out of handles to create new process IDs.

What is the purpose of package raclient in SFOS? What triggers raclient to run the shell script raclient.sh? Where in SFOS is the configuration that tells networkd to run raclient -s /scripts/network/raclient.sh?

raclient stands for Router Advertisement Client.

I am still hoping someone can describe where it fits in the flow of IPv6 on SFOS.

When raclient is listening on an interface raclient runs raclient.sh every time a router advertisement packet is received.

Hello there,

DEV provided an RCA for your closed case with ID NC-124721.

You can open a ticket requesting the full details of the RCA, but essentially, what is happening is that networkd is ignoring the signal (SIGCHDL) and is not removing the dhclient process from the child process list; this process repeats over time, leading to an accumulation of multiple dhclient child processes.

Networkd has not had a problem acknowledging the termination of dhclient child processes on my production and test firewalls
