syslog duplicate all content

I have a problem that anything that printed to syslog file is appear as duplicate. My search on network show me that /etc/rsyslog.conf contain attribute that should avoid such thingRepeatedMsgReduction on Unfortunately it just have no influence on my machine. After deep investigation I found what cause a duplication : There are two lines I add to rsyslog.conf that take care log size rotation. I mean they used rotate syslog by size $outchannel syslog_rotation,/var/log/syslog,2621440,/root/scripts/systemlogs.sh *.* :omfile:$syslog_rotation I know you will ask why you didn't use "maxsize" attribute on logrotate, but after I check it it didn't work on my machine too. The content of systemlogs.sh is as bellow : #!/bin/bash /usr/sbin/logrotate -f /etc/logrotate.d/rsyslog I will show an example of my syslog that contain duplications : 5,1,29/06/2017 16:24:21.319213,SCR-172D2A,PM:, Sent 'Farm ID set' to RF module A.
