Description Jonas H. 2013-05-06 21:08:38 UTC

Weird behavior regarding journalctl -n: Increasing the -n argument by 1 changes the output completely

$ journalctl -n 1002 | head
-- Logs begin at Tue 2013-04-09 12:08:24 CEST, end at Sun 2060-02-15 19:22:01 CET. --

May 06 22:15:06 x201 ...

$ journalctl -n 1003 | head                                                                                                                                                                             23:05 
-- Logs begin at Tue 2013-04-09 12:08:24 CEST, end at Sun 2060-02-15 19:22:01 CET. --
May 06 13:01:29 x201 ...
-- Reboot --
May 06 13:40:09 x201 ...

Just look at the time stamps. Doesn't make too much sense if -n should behave similar to head/tail's -n.

Can you check if http://cgit.freedesktop.org/systemd/systemd/commit/?id=87011c25d9 fixes things for you? Also,
http://cgit.freedesktop.org/systemd/systemd/commit/?id=cbd671772 should fix one the ways that looped journals are produced, but it won't immediately help if you have such journals currently.

Comment 2 Jonas H. 2013-06-12 07:59:33 UTC

Can't reproduce it in the old version right now so I really can't say anything.

I'll try again in a few days.
