You have been subscribed to a public bug: Hello,
my system takes a rather long time to shutdown (~7-10 sec.) while there are often error messages flashing on the screen like: - Killing all remaining processes failed - Mount: / is busy To investigate the problem, I patched my /etc/init.d/umountfs and umountroot scripts with the proposed changes from https://code.launchpad.net/~jamesodhunt/ubuntu/saucy/sysvinit/log- processes-and-open-files-on-shutdown/+merge/163740 to log open files at shutdown and attached the resulting shutdown-lsof.log here. The only thing in that log that looks suspicious to me are the ones regarding dhclient: dhclient 5786 1 0 cwd DIR 252,5 4096 2 / dhclient 5786 1 0 rtd DIR 252,5 4096 2 / dhclient 5786 1 0 txt REG 252,5 1659968 654751 /sbin/dhclient dhclient 5786 1 0 mem REG 252,5 52168 786517 /lib/x86_64-linux-gnu/libnss_files-2.17.so dhclient 5786 1 0 mem REG 252,5 1848024 786477 /lib/x86_64-linux-gnu/libc-2.17.so dhclient 5786 1 0 mem REG 252,5 149312 786464 /lib/x86_64-linux-gnu/ld-2.17.so dhclient 5786 1 0 4w REG 252,5 1058 21443 /var/lib/NetworkManager/dhclient-8f9a3dff-24e6-4374-b0b2-c38524cdc0ce-eth0.lease Maybe there is some problem shutting down NetworkManager? I found the respective dhclient entries on two separate shutdown logs.
