According to [1], this should be fixed. I remember getting a small number of messages like that, too, on my laptop. However, it's at the university, so I can't check now to see what types of messages were missed (if any; if I understand [1] correctly, those messages are most likely bogus?). But yeah, that's any idea, Covici: see what's in /var/log/messages, compare that to the journalctl output, and check if any messages were actually missed ("diff -U" might be of help here). And if/once you did that, what kinds of messages were missed, if any? If those messages really are bogus, you shouldn't see any differences between the two. > Regards. > > https://github.com/balabit/syslog-ng/issues/314 Note that that fix would only be in the ~arch version of syslog-ng, the current stable version (3.4.8) is a few months too old. -- Marc Joliet -- "People who think they know everything really annoy those of us who know we don't" - Bjarne Stroustrup
