Dear Monks,

Following is the code which runs fine on any machine. But If I submit this job to a cluster to run in batch mode, this script goes to sleep mode.
## Runs fine devarajk>/u/devarajk/downloads/check_cvs.pl
## This goes to sleep mode devarajk>sqrsh -grid desa /u/devarajk/downloads/check_cvs.pl
sqrsh is a utility we use to submit jobs to clusters. 

#!/usr/local/bin/perl -w

use Data::Dumper;
use Cvs;

my $repository = "prod.nyc.com:/proj/ops/repository";

my $dir        = "/tmp/";

my $cvs_obj = new Cvs (
                       $dir,
                       cvsroot => $repository,
                       "remote-shell" => 'rsh',
                       "debug" => 1,
                      ) or die $Cvs::ERROR;
my $res = $cvs_obj->checkout(".");
print Dumper($res);
print "Successfully initialized cvs object for repository $repository 
+and checked out in $dir\n";

I traced the code to where it sleeps. Its in IPC/Run.pm 
       $nfound = select(
            $self->{ROUT} = $self->{RIN},
            $self->{WOUT} = $self->{WIN},
            $self->{EOUT} = $self->{EIN},
            $timeout
                         ) ;

IPC/Run.pm is called by Cvs/Command/Base.pm
The code actually checks out the repository but goes to sleep mode.
Any help would be appreciable. Is it related to STDOUT/STDIN buffer problems?
Thanks,
Kumaravel
