I have logrotate running on a RedHat system. I changed the configuration to rotate all files in a folder daily. A few days later file listing is showing this:

login.log-20170220

I have that same setup in other systems and never had this issue... Here is the configuration in logrotate.d/

/var/log/syslog-wal/* {
    missingok
    notifempty
    create 0640 root wheel
    daily
    rotate 14
}

I find it peculiar that every 8 days there is a new round of files. Any clue of what's going on? This folder is inside of /var/log, but I didn't see anything in the other standard logrotate.d files that could explain this.

The pattern /var/log/syslog-wal/* matches not only login.log but also all the rotations of that log, which means that every single file will be rotated and have the date appended to their name (if the file fulfills the rotation criteria).

When run again, each of those files will have the date appended, etc.

So the solution is to just specify /var/log/syslog-wal/login.log, or possibly /var/log/syslog-wal/*.log, as the pattern.
