Hi,

I see this in my error log as well, and it appears to happen only when
I
restart nginx… It does mean sometimes the restarts fail.

How did you restart nginx ?

This message is issued by perl. I had fixed it once.
However, I do not know the cause of modern message.

Using the init.d scripts

Source function library.

. /etc/rc.d/init.d/functions

Source networking configuration.

. /etc/sysconfig/network

Check that networking is up.

[ “$NETWORKING” = “no” ] && exit 0

nginx="/usr/sbin/nginx"
prog=$(basename $nginx)

NGINX_CONF_FILE="/etc/nginx/nginx.conf"

[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx

lockfile=/var/lock/subsys/nginx

start() {
[ -x $nginx ] || exit 5
[ -f $NGINX_CONF_FILE ] || exit 6
echo -n $"Starting $prog: "
daemon $nginx -c $NGINX_CONF_FILE
retval=$?
echo
[ $retval -eq 0 ] && touch $lockfile
return $retval
}

stop() {
echo -n $"Stopping $prog: "
killproc $prog -QUIT
retval=$?
echo
[ $retval -eq 0 ] && rm -f $lockfile
return $retval
}

restart() {
configtest || return $?
stop
start
}

I guess … it couldn’t full stop nginx daemon and then create new
process .
you can try edit the script like this and try restart again:

…

restart() {
configtest || return $?
stop
sleep 2
start
}
