Problem example:

Greping processes:
root      1874  0.0  0.0   3112   580 ?        Ss   00:56   0:00 dhclient3 -pf /var/run/dhclient.eth2.pid -lf /var/lib/dhcp3/dhclient.eth2.leases eth2

Then, you give: kill 1874

And of course the process is gone from the process list.

But the /var/run pid file remains there:

mordor:/lib/modules# l /var/run/dh*
-rw-r--r-- 1 root root 5 2007-02-24 00:56 /var/run/dhclient.eth2.pid
mordor:/lib/modules#

I guess this should not happen. Pid file should be gone...

Hi,

This bug was reported in Debian, and from a quick peruse of the source code,
I can't find much evidence in the way of signal handlers at all. Either way,
it seems that dhclient could do a better job of cleaning up after itself if
it is terminated. The lock file being left behind doesn't seem to cause any
problems though.

Please maintain the Cc line to keep our BTS in the loop.

regards

Andrew
