I see some strange Apache restarts in my VPS's logs, and they seem to be related to DirectAdmin's daily tally and monthly reset, as the times the restarts happen match with these DirectAdmin cron jobs. Apache restarts twice, one minute apart. To me, this doesn't look like intended behavior.
What's going on here? What can be done about it?
From Apache error log:
$ cat /etc/cron.d/directadmin_cron :
$ cat /etc/centos-release
$ uname -r
$ ./build versions
