The following is a cut/paste of your code with the addition of use strict;use warnings;, the addition of variable declaration, removing your LOG line and substituting "echo" for "/home/admin/bin/email.ksh".

use strict;
use warnings;

my $LOGFILE = 'junk.txt';
open my $FH, "<$LOGFILE" or die "Failed to open $LOGFILE";
    
my @contents = ();
while (my $LINE = <$FH>) {
    push @contents, $LINE;
}
close $FH;
        
my @args = ("echo", "@contents", "Web Server Issue", "PROD", "/home/ad
+min/logs/check_jvm/EmailAlert.log");
system(@args) == 0 or die "system @args failed: $?"

It echos The contents of the file. Web Server Issue PROD /home/admin/logs/check_jvm/EmailAlert.log as expected. Are you sure you are invoking your shell script properly? Can you invoke it successfully from the command line? If it comes down to debugging a shell script or perl, I'd be inclined to suggest putting time in on hbm's suggestion.
