#2 Docker logs to syslog drivers freezed

State: - host: LXC 5.15.131-1-pve - docker version 24.0.5 - rsyslog on host listen 514 port with local3 facility:

# cat /etc/rsyslog.d/docker.conf 
local3.*        /var/log/docker.log
# & stop

- containers configured to syslog drivers:

       logging:
        driver: "syslog"
        options:
          syslog-address: "udp://127.0.0.1:514"
          syslog-facility: "local3"

- Some changes have been made in file /var/log/docker.log

Problem: - Collecting logs from containers stopped after that - Restart rsyslogd - no success, Service work - Restart containers (not all compose file) - no success. - No logs by test:

docker run --log-driver syslog --log-opt syslog-facility=local3 --log-opt syslog-address=udp://127.0.0.1:514 alpine echo '999999'`
