Someone must have seen this one but it reappears in each new version,
so I'll make an "official" report.  The following file is included in the
rpm as junkbuster.logrotate to be placed in /etc/logrotate.d:

# Logrotate file for Junkbuster RPM

/var/log/junkbuster/* {
	compress
        weekly
}

Specifying * as the file(s) to be rotated results in a geometric growth
of the number of files in /var/log/junkbuster because each run of
logrotate rotates each _generation_ of the log file instead of just the
base file.   The corrected configuration file should, of course, look
like this:

# Logrotate file for Junkbuster RPM

/var/log/junkbuster/junkbuster{
	compress
        weekly
}
