Description Jonas H. 2013-05-06 21:02:56 UTC 
To reproduce:

In terminal 1:
$ sudo journalctl -f

In terminal 2:
$ sudo ls

What happens? journalctl re-outputs all the journal content
What is expected to happen? journalctl should stay in the same state.

Version 202 on Arch Linux

I can't reproduce this with systemd 208 on Centos 7.0.1406
Comment 3 Zbigniew Jedrzejewski-Szmek 2014-11-27 05:39:44 UTC 
This was definetely an issue (I saw it myself a few times). I think it was caused by loops (or rather jumps) in the journal reading code, and we fixed a bunch of those during the last year. I'll mark this as fixed, please reopen if it happens again with systemd >= 217.
