      ^^---- the uninitialized value is here

[download]

You do 

print "$PID|$SID|",shift(@flds),"|$date\n";

[download]

but sometimes the value shifted off @flds is undef. Quick fix: 

print "$PID|$SID|",(@flds ? shift(@flds) : ''),"|$date\n";

[download]

But if those output lines containing an empty 3rd field are unwanted anyways, say 

print "$PID|$SID|",shift(@flds),"|$date\n" if $flds[0];

Why are you 

my @dates_copy = @dates;

[download]

copying @dates each pass through the loop? Just iterate over @dates.
