I noticed that "systemctl daemon-reexec" just kill somehow last staled process, if I have second staled process. This is the output after daemon-reexec: --- Warning! D-Bus connection terminated.

Problem is, starting today after working perfectly up till yesterday, this script now hangs on Ubuntu 15.04. When run from cron, the process tree looks like this: service smbd restart \_ systemctl restart smbd.service \_ /bin/systemd-tty-ask-password-agent --watch \_ /usr/bin/pkttyagent --notify-fd 5 --fallback Run from a shell via sudo, same thing except the process tree (obviously) includes the sudo command. It times out after 5 minutes, causing the script to fail. If I manually kill the processes, it fails faster. The simplest possible scripts that reproduce this, run as root or through cron or via sudo, are: #!/bin/sh service smbd restart #!/bin/sh systemctl restart smbd.service Using 'service', this works perfectly on Ubuntu 14.04 and 14.10, and until this morning worked perfectly on 15.04 as well. 1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu Ubuntu 15.04 2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center systemd 219-7ubuntu5 samba 2:4.1.13+dfsg-4ubuntu3 3) What you expected to happen Services to restart 4) What happened instead Services didn't restart, 'systemctl' hung To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1456789/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
