Wierd hanging behavior

[neiljones]

I have a moderately large and involved script which has suddenly and inexplicably decided to do absolutely nothing. I run it and it just hangs. I am running it over an SSH connection to a server. When I run it I find that I can actually type stuff
on the screen ( when it is not designed to take any input at all) and that CTRL C will stop it.

Putting as the first executable line a simple print statement produces nothing.
However cutting out the first few lines and pasting themto a new program gives a program that runs perfectly.
What on earth is causing this. Here are the lines that work.


print "hello";
open( IN, "datas2.txt" ) || die "cannot open for reading: $!";
@datalines=<IN>;
close(IN);
$pcount = 0;

print "##################################################################################################";

well.. without seeing anything other than the working code who knows.. but you should go through it one line at a time and add debug statemetns.
