Package: dash
Version: 0.5.5.1-2
Severity: important
I started an aptitude safe-upgrade and left the computer for half an
hour. Upon return I find that there's a suspicious process eating 100%
of a CPU for a long time. /proc/pid/cmdline says:
# cat cmdline
/usr/bin/perl-w/usr/share/debconf/frontend/var/lib/dpkg/info/dash.postinstabort-upgrade0.5.5.1-2.3
strace'ing the process yields this:
ioctl(0, SNDCTL_TMR_TIMEBASE or TCGETS, {B0 -opost -isig icanon -echo ...}) = 0
ioctl(0, SNDCTL_TMR_TIMEBASE or TCGETS, {B0 -opost -isig icanon -echo ...}) = 0
ioctl(0, SNDCTL_TMR_TIMEBASE or TCGETS, {B0 -opost -isig icanon -echo ...}) = 0
<repeats ad nauseam>
Killing that process and doing an "aptitude install dash" reports this:
# LC_ALL=C sudo aptitude install dash
