Actually I cannot reproduce this issue. Can you try to set PersistStateInterval for imjournal to 1? If this works, this is expected behavior. With reloading of journal or rsyslog itself, it comes the price. It is technically impossible to handle duplication of messages. Duplication is always =< PersistStateInterval. But PersistStateInterval = 1 has impact on performance. |
Description of problem: Journal is reloaded and duplicate messages are output into log file. Version-Release number of selected component (if applicable): rsyslog-8.24.0-12.el7.x86_64 How reproducible: Steps to Reproduce: 1. Disable the rate-limiting of journald. -/etc/systemd/journald.conf RateLimitInterval=0 2. Execute the command below. # for i in `seq 1 3000`;do logger -p local5.info "modify syslog rate limit modify 1640: $i" ;done 3. Check /var/log/messages. Actual results: Journal reloaded and some duplicate messages are output to log file. ~~~ Sep 14 20:19:01 R74Router root: modify syslog rate limit modify 1640: 871 Sep 14 20:19:01 R74Router root: modify syslog rate limit modify 1640: 872 Sep 14 20:19:01 R74Router root: modify syslog rate limit modify 1640: 873 Sep 14 20:19:01 R74Router root: modify syslog rate limit modify 1640: 865 < Sep 14 20:19:01 R74Router root: modify syslog rate limit modify 1640: 866 < Sep 14 20:19:01 R74Router root: modify syslog rate limit modify 1640: 867 < Sep 14 20:19:01 R74Router root: modify syslog rate limit modify 1640: 868 < Sep 14 20:19:01 R74Router root: modify syslog rate limit modify 1640: 869 < Sep 14 20:19:01 R74Router root: modify syslog rate limit modify 1640: 870 < Sep 14 20:19:01 R74Router root: modify syslog rate limit modify 1640: 871 < Sep 14 20:19:01 R74Router root: modify syslog rate limit modify 1640: 872 < Sep 14 20:19:01 R74Router root: modify syslog rate limit modify 1640: 873 < Sep 14 20:19:01 R74Router root: modify syslog rate limit modify 1640: 874 Sep 14 20:19:01 R74Router rsyslogd: imjournal: journal reloaded...
