Package: irqbalance
Version: 1.5.0-2
Severity: serious
On one of my systems (not the one I'm writing the report on), a
Raspberry Pi 2 with Debian Sid armhf and sysvinit, the terminal which I
ran the upgrade in, looked like this (excerpt):

The box was using all available swap (2GB) and threw errors like this:
zsh: pipe failed: too many open files in system
Looks as if some recursive systemctl call (why at all on a system with
sysvinit-core?) horribly went wrong.
(When killing all the systemctl processes with killall -TERM, the load
peaked at close to 1000. Still waiting for it to finish...)

I found even more remainders of a previously installed systemd on that
particular Raspberry Pi:

Despite I can't remember any crash of that system during a package
upgrade, 3.5 years are a long time and it looks to me as if maybe an
fsck restored some already deleted files after a crash directly after
switching to sysvinit while /var/lib/dpkg/status stayed intact.
Definitely an issue of that specific system, and not of the package,
hence closing. Sorry for the noise.
Will try to clean this up by installing systemd and purging it again.
Felipe: Thanks again for giving the right hint to discover that! I'm
actually surprised that the system ran for 3.5 years with Sid and
nearly daily dist-upgrades without any obvious issues. In some way
Regards, Axel
