Package: network-manager
Version: 1.0.2-2
Severity: normal
File: /usr/sbin/NetworkManager
When doing suspend/resume cycles that switch the network connection (eth0
to wlan0 or usb0), NetworkManager still has the dhclient process that it
spawned earlier on - which is a zombie already.
11240 ? Ssl 0:23 /usr/sbin/NetworkManager --no-daemon
9502 ? Z 0:00 \_ [dhclient] <defunct>
As long as NetworkManager is blocked, no new network connection gets
established - and clients like the KDE widgets also hang, therefore
blocking eg. the screen saver lock and suspend cycle when the laptop is
simply closed...
The event order is typically
* suspend (to ram),
* disconnect eth0,
* later on resume
* and then the above situation is present.
Sometimes it's just not reaping the process, but starting a new dhclient:
17544 ? Ssl 0:01 /usr/sbin/NetworkManager --no-daemon
20135 ? Z 0:00 \_ [dhclient] <defunct>
23232 ? S 0:00 \_ /sbin/dhclient -d -q -sf /usr/...

Version: 1.58.0-1
dhclient support was removed upstream in 1.58.0, making this bug report
obsolete. Thus closing.
