How about doing all of this in one single awk script only? The following is for showing the concept only; not having access to a solaris system, I can't test my proposal.

Code:

zoneadm list -iv | awk '(length($4) > 3) &&( $4 !~ "PATH") {print $4)'

do the same?

Code:

while read ZONE
do
    echo "$ZONE"  >> $MSG
    echo "--------------------------------------" >> $MSG
    cat $ZONE/root/var/spool/cron/crontabs/root | grep "/shutdown" >> $MSG
    echo "\n" >> $MSG
done < "$ZONES"

.
.
.

means: for all zones found above print the lines containing "/shutdown" from the crontab files for all the zones found.
Doesn't

Code:

zoneadm list -iv | 
awk '
(length($4) > 3) && 
($4 !~ "PATH")  {CRP = $4 "/root/var/spool/cron/crontabs/root"
                 while (1 == getline LN < CRP)  if (LN ~ /\/shutdown/)  {print $4
                                                                         print "---------"
                                                                         print LN
                                                                        }
                 close (CRP)
                }
' > $MSG

do the same?
