KernelCare Logrotate Configuration Fails with "Anacron job 'cron.daily' on $DOMAIN.TLD" Error – cPanel

Symptoms

The following notification/alert email is received:

Subject: Anacron job 'cron.daily' on $DOMAIN.TLD

/etc/cron.daily/logrotate:

error: libcare:3 bad rotation count '5 # keep 5 last archives' 
error: found error in /var/log/libcare/*.log , skipping

Description

The issue is related to an incorrectly formatted comment in this logrotate configuration file from the Kernelcare package:

cat /etc/logrotate.d/libcare

/var/log/libcare/*.log {

daily

rotate 5 # keep 5 last archives

missingok # it's ok if there is no such file

notifempty # do nothing if file is empty

compress

}

As seen here this file is responsible to rotate the log files in this directory:

/var/log/libcare/

The logrotate command is configured to run every day and when it runs the above configuration is consequently triggered:

cat /etc/cron.daily/logrotate

#!/bin/sh

export TMPDIR=/var/spool/logrotate/tmp

/usr/sbin/logrotate -s /var/lib/logrotate/logrotate.status /etc/logrotate.conf

EXITVALUE=$?

if [ $EXITVALUE != 0 ]; then

/usr/bin/logger -t logrotate "ALERT exited abnormally with [$EXITVALUE]"

fi

exit 0

You can reproduce the issue by running the above command manually and tailing the cron log file like this:

/usr/sbin/logrotate -s /var/lib/logrotate/logrotate.status /etc/logrotate.conf; tail -f /var/log/cron

error: libcare:3 bad rotation count '5 # keep 5 last archives'

error: found error in /var/log/libcare/*.log , skipping

Oct 8 06:54:01 server CROND[12754]: (root) CMD (/usr/bin/jetcli backup --run snapshots > /dev/null 2>&1)

........

Workaround

There is a simple workaround this issue and that is to simply remove the comment "# keep 5 last archives" after the rotation count " rotate 5" in this file:

/etc/logrotate.d/libcare

This will stop the error messages.
