[DragonFlyBSD - Bug #2732] dhclient sporadically eats up all processing time

[bugtracker-admin at leaf.dragonflybsd.org]

Issue #2732 has been updated by masu.


Thanks, I applied your patch and the laptop has been running for >7h without dhclient showing up as described. dhclient normally showed up earlier before applying your patch.

Looks promising ...

Hi,

my wifi interface is configured in rc.conf to run with DHCP.
After logging into the machine (Lenovo ThinkPad X61) one can see two dhclient instances running on that wifi interface, one run by _dhcp and one run by root.
The one run by user _dhcp then uses >97% processing time of one of the machine's cores.
This behaviour has been around since v3.6 (this is the version I started with dfly).

Is it normal that two chclients are running by differnet users (_dhcp, root)?

uname -a output is:

DragonFly MisterX 4.1-DEVELOPMENT DragonFly v4.1.0.53.g61b98-DEVELOPMENT #1: Sun Nov 9 16:10:57 CET 2014 root at MisterX:/usr/obj/usr/src/sys/X86_64_GENERIC x86_64

Regards
Matthias
