RHBA-2020:1994 - Bug Fix Advisory

Topic

An update for systemd is now available for Red Hat Enterprise Linux 7.7
Extended Update Support.

Description

The systemd packages contain systemd, a system and service manager for
Linux, compatible with the SysV and LSB init scripts. It provides
aggressive parallelism capabilities, uses socket and D-Bus activation for
starting services, offers on-demand starting of daemons, and keeps track of
processes using Linux cgroups. In addition, it supports snapshotting and
restoring of the system state, maintains mount and automount points, and
implements an elaborate transactional dependency-based service control
logic. It can also work as a drop-in replacement for sysvinit.

Bug Fix(es) and Enhancement(s):

• [FJ7.8 Bug]: systemd: restarting systemd-journald.service fails

(BZ#1807796)

• systemd leaks memory (in dbus) and spends its time sending

PropertiesChanged notifications (BZ#1817503)

• Lazy setup of inotify_fd in sd-journal may cause clients to leak file

descriptors (BZ#1820072)

Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.
