The actual situation is today the same than yesterday. The system is writing to the old files.
using a systemctl kill -s HUP --kill-who=main rsyslog.service didn't help. The system was still writing to the old syslog.1-file while the new syslog content's kern.log messages. Only a pkill -HUP rsyslogd helped. the kernel is Linux debian64 5.10.17-v8+ #1414 SMP PREEMPT Fri Apr 30 13:23:25 BST 2021 aarch64 GNU/Linux cat /etc/os-release PRETTY_NAME="Debian GNU/Linux 10 (buster)" NAME="Debian GNU/Linux" VERSION_ID="10" VERSION="10 (buster)" VERSION_CODENAME=buster ID=debian HOME_URL="https://www.debian.org/"; SUPPORT_URL="https://www.debian.org/support"; BUG_REPORT_URL="https://bugs.debian.org/"; ---------------------- Looking on a second server with the original /usr/lib/rsyslog/rsyslog-rotate -version and kernel Linux localhost 4.19.0-16-amd64 #1 SMP Debian 4.19.181-1 (2021-03-19) x86_64 GNU/Linux cat /etc/os-release PRETTY_NAME="Debian GNU/Linux 10 (buster)" NAME="Debian GNU/Linux" VERSION_ID="10" VERSION="10 (buster)" VERSION_CODENAME=buster ID=debian HOME_URL="https://www.debian.org/"; SUPPORT_URL="https://www.debian.org/support"; BUG_REPORT_URL="https://bugs.debian.org/"; Here everything works fine.
