Hello,
> Synopsis: Memory leak in dhclient(8) on OpenBSD-current
> Category: system
> Environment:
System : OpenBSD 6.2
Details : OpenBSD 6.2-beta (GENERIC.MP) #59: Tue Aug 29 15:56:07 MDT 2017
[email protected]:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
> Description:
On OpenBSD-current when a network interface is configured to use dhcp and if
it is
physically disconnected (e.g. cable is unplugged or WiFi hotspot is not
available)
than dhclient goes to "sleep" and starts to leak memory very rapidly.
This problem doesn't appear in OpenBSD 6.1.
> How-To-Repeat:
Configure your /etc/hostname.if to use dhcp and make sure that this network
interface is not physically connected to the network. Reboot and watch
dhclient's
memory leak with top(1) or htop(1).
> Fix: Unknown
