Hi Monks, This is Srinivas, a beginner in Perl.

I was trying to connect to remote system by using Net::SSH::Perl module . I have installed all the required modules for this module to work and tried my hand on writing a small script by embeding it in multi threads. Here is the code 

#!/usr/bin/perl
use Net::SSH::Perl;
use threads;

$filepath="/tmp/Perl/host.conf";

if(open(FILE, $filepath))
{

$inputline=<FILE>;

        while($inputline ne "")
        {
        chomp($inputline);
                if($inputline !~ /#/)
                {
                if( @array = split(/:/,$inputline) )
                {
                        $host = $array[1];
                        $user = $array[2];
                        $pass = $array[3];
                        print "\n\n\n ------ CHECK1 $user $host $pass 
+\n\n\n\n\n ";
                        push @threads, threads->create(\&method, $host
+, $user, $pass);

                } #if2
                } #if1
                $inputline=<FILE>;
        } #while

while ( my $thread = shift @threads ) {
              $thread->join ;
              print " Thread [ $host ] Ending ... \n";
          }
}
else
{
        die " File doesn't exists "
}


sub method
{
my($hst,$usr,$pas)=(shift,shift,shift);
        &thrds($hst, $usr, $pas);
}

sub thrds
{
my($h,$u,$p)=(shift,shift,shift);

 $ssh = Net::SSH::Perl->new($h,debug=>'true');
 $ssh->login($u,$p);

my($stdout, $stderr, $exit) = $ssh->cmd('hostname');
my($stdout, $stderr, $exit) = $ssh->cmd('ls -l');
print $stdout;
$ssh->close();
}

When I execute the above code with only two threads, the CPU is going upto 100% and system is getting hanged. My ram size is appriximately 4GB. I have no problem with a single thread or when executed without threads.

Did I mis-configured any thing. Please help me.

Thanks in advance,

Srinivas.
