Public bug reported: If irqbalance is started with the "--policyscript" option, Upstart is unable to manage it properly (bug #406397 is being triggered), and stopping/restarting it fails. Noticed this when the 1.0.6-2ubuntu0.14.04.2 update hit Trusty yesterday. See below:
$ /sbin/stop irqbalance irqbalance stop/waiting $ echo 'OPTIONS="--policyscript=/bin/true"' >> /etc/default/irqbalance $ /sbin/start irqbalance irqbalance start/running, process 23862 $ /sbin/status irqbalance irqbalance start/running, process 23862 $ pgrep -a irqbalance 23859 /usr/sbin/irqbalance --policyscript=/bin/true 23871 /usr/sbin/irqbalance --policyscript=/bin/true [note how the PIDs don't match what Upstart believes them to be] $ /sbin/stop irqbalance [hangs] ^C $ /sbin/status irqbalance irqbalance stop/killed, process 23862 $ pgrep -a irqbalance 23859 /usr/sbin/irqbalance --policyscript=/bin/true 23871 /usr/sbin/irqbalance --policyscript=/bin/true $ /sbin/start irqbalance [hangs] I successfully recovered from this situation by running the hack at https://raw.githubusercontent.com/ion1/workaround-upstart-snafu/master /workaround-upstart-snafu on all the servers that had attempted to upgraded the irqbalance package. One easy way to fix this issue is to remove "expect fork" and instead start irqbalance with the "--foreground" option. Patch attached. On a related note, I see that the irqbalance package ships both a SysV init script in /etc/init.d/irqbalance as well as an Upstart job definition. That's rather confusing to a sysadmin, and could possibly lead to collisions? As I understand it, the SysV init script for an Upstart-managed service is supposed be replaced by a symlink to /lib/init/upstart-job. Maybe you'll want to look into that as well.
