[DragonFlyBSD - Bug #2732] dhclient sporadically eats up all processing time
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 ... Bug #2732: dhclient sporadically eats up all processing time http://bugs.dragonflybsd.org/issues/2732#change-12330 * Author: masu * Status: New * Priority: Normal * Assignee: * Category: * Target version: 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@MisterX:/usr/obj/usr/src/sys/X86_64_GENERIC x86_64 Regards Matthias ---Files 0001-dhclient-Update-linkstate-after-poll.patch (1.14 KB) 0001-dhclient-Update-linkstate-after-poll.patch (972 Bytes) -- You have received this notification because you have either subscribed to it, or are involved in it.

Issue #2732 has been updated by jorisgio. I experience this issue too from time to time. There is two processes because of privsep, the actuall dhcp code runs in _dhcp while the controlling process runs as root.
