Package: systemd
Version: 215-17+deb8u4
Severity: important

Dear Maintainer,

systemd-journald is deleting log messages when it shouldn't, it is not respecting SystemMaxUse and SystemKeepFree as configured in /etc/systemd/journald.conf

   * What led up to the situation?
editing /etc/systemd/journald.conf

This is the current state of disk space:
$ df -h
Dateisystem    Größe Benutzt Verf. Verw% Eingehängt auf
/dev/sda1       4,6G    3,9G  424M   91% /

   * What was the outcome of this action?
$ systemctl status systemd-journald
systemd-journal[1086]: Permanent journal is using 504.1M (max allowed 750.0M, trying to leave 50.0M free of 451.2M available → current limit 504.1M)

   * What outcome did you expect instead?
I expect that systemd-journald would set the "current limit" in a way that leaves 50.0M of free space. The way the "current limit" is being calculated seems to be broken at the moment.
