<pre>Problem
--------------------
systemd-journal consumes 100% cpu only if the getty.target is started.
The getty.target can be started for /dev/console or for /dev/tty1 (logical pts
console) - no difference.
Without getty.target and an installed sshd daemon, the system works fine.
The strace is very simular to the strace in <a class="bz_bug_link

title="RESOLVED FIXED - systemd-journald eats 100% CPU"
href="show_bug.cgi?id=61191">BUG 61191</a>, but MaxRetentionSec in
journald.conf is not set.
