If the /var/log/maillog file is stuck writing, restarting the rsyslog service may help in resolving the issue.
service rsyslog restart
However, it is important to understand the potential impact of restarting the rsyslog service, as it can affect the logging for other services running on the server.
Before restarting the rsyslog service, you can check the current status of the service by running the command:
systemctl status rsyslog
If the status shows that the service is not running, you can try starting it by running the command:
systemctl start rsyslog
If the service is already running and restarting it doesn’t resolve the issue with /var/log/maillog, you may need to investigate further to determine the root cause of the problem.
It is also a good practice to backup important log files before making any changes to the system.
