[Asterisk-Users] Daily Reboot Script for Asterisk Question

[Min Hwan Chang]

Currently I'm using the daily reboot script for asterisk and I was
just wondering what the following line actually does:
while /bin/ps ax | /bin/grep '[s]afe_asterisk' >/dev/null; do sleep 5; done

It is from this script which I'm running through crontab:
/usr/sbin/asterisk -rx "stop when convenient"
while /bin/ps ax | /bin/grep '[s]afe_asterisk' >/dev/null; do sleep 5; done
/sbin/rmmod wctdm
/sbin/modprobe wctdm
/usr/sbin/safe_asterisk

Yes I understand that daily reboot is unnecessary but until I find the
problem, this works for our needs.  I'm wondering what that line does
because last night when the Cron job started running, it kept running
the job over and over until I got an out of memory error... as seen
below:
