            Bug ID: 55615
          Assignee: systemd-bugs at lists.freedesktop.org
           Summary: journalctl -f stops following new logs unexpectly when
                    new logs are coming too fast
        QA Contact: systemd-bugs at lists.freedesktop.org
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: felixonmars at gmail.com
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: unspecified
         Component: general
           Product: systemd

This seems a different bug than #54623.

If I use journalctl -f in terminal, when new logs coming too fast (for example,
rtkit with a wine directx programs, which will produce per-user limit exceeded
logs several times per second), it stops sometimes and no new logs are shown.

If I use journalctl (without -f) and hit shift-G again and again, no such
problem exists (even if the -f one is currently blocking).

Using systemd 194.
