Hourly daemon restarts

[RocketJSquirrel]

My log shows this sequence every hour, on the .260 firmware:

Nov 11 08:59:57 notify_rc : restart_radvd
Nov 11 08:59:57 notify_rc : restart_diskmon
Nov 11 08:59:57 rc_service: restart_diskmon is waitting restart_radvd...
Nov 11 08:59:57 radvd[3991]: Exiting, sigterm or sigint received.
Nov 11 08:59:57 radvd[3991]: sending stop adverts
Nov 11 08:59:57 radvd[3991]: removing /var/run/radvd.pid
Nov 11 08:59:57 radvd[4005]: version 1.9.1 started
Nov 11 08:59:58 disk monitor: be idle

It's not a problem, but it makes me suspicious. In general, when a process is being restarted regularly, I suspect a memory leak which the developers couldn't fix. Restarting is the brute force method of avoiding the leak.

Just curious. Anybody have any insight on this?

Yes, I saw this too, and looked it up. This is the way that it's supposed to work for IPv6, the advertising daemon is supposed to restart and say hello every hour. This is part of the whole IPv6 networking picture. If you do some googling on radvd and diskmon, you'll find this.

My log only shows the diskmon part.

Do you have IPv6 enabled? Radvd is associated with IPv6 use.

 

[lfbb]

I don't have IPv6 enabled, that's it.
