Re: Can't use an undefined value as an ARRAY reference

That means $self->{'netstat_array'} is sometimes undefined, which means it doesn't contains a reference to an array.

If it's suppose to be undefined at times, then maybe you're looking for

$self->{'netstat_array'} ||= [];
return scalar @{ $self->{'netstat_array'} }, $self->{'netstat_array'};
