audit log still getting rotated even with max_log_file_action = ignore?

[Bond Masuda <bond.masuda@jlbond.com>]

I'm seeing my /var/log/audit/audit.log getting rotated (I find a audit.1
or audit.2, etc. file) even though I have max_log_file_action=ignore.
Here's the full auditd.conf:

log_file = /var/log/audit/audit.log
log_format = RAW
log_group = root
priority_boost = 4
flush = INCREMENTAL
freq = 20
num_logs = 5
disp_qos = lossy
dispatcher = /sbin/audispd
name_format = hostname
max_log_file = 6
max_log_file_action = ignore
space_left = 75
space_left_action = email
action_mail_acct = root
admin_space_left = 50
admin_space_left_action = exec /usr/local/bin/remove_oldest_audit_log
disk_full_action = exec /usr/local/bin/remove_oldest_audit_log
disk_error_action = SUSPEND
tcp_listen_queue = 5
tcp_max_per_addr = 1
tcp_client_max_idle = 0
enable_krb5 = no
krb5_principal = auditd

what am I missing?

I have a cron job in /etc/cron.daily/auditd that I use to rotate +
compress the audit logs, but this is not what is causing the audit log
rotation.

Is there another setting I must set in order for it to not automatically
rotate the audit log? How do I achieve the desired effect, where the
audit log is only rotated when my cron script runs?

Thanks,
Bond
