I am launching an external program through perl script using backticks. But I am facing an issue. Although the external program gets launced, the control is not given back to the perl script (a print statement immediately after this does not execute). I used system instead of backticks but still the issue persists. When I use the same backtick command in another perl script , it works fine. Any help greatly appreciated. Here is the code 
Here is the code:

sub start_CM_Synergy() {
  my ($database_name) = @_;
  my $dbData = `grep $database_name /common/gm/scripts/dbInfo`;
  
  if($dbData eq "") {
    return 1;
  }
  
  my @Fld = split(/\s+/, $dbData);
  $dbName = $Fld[0];
  $dbId = $Fld[1];
  $ccm_home = $Fld[2];
  $dbEnghost = $Fld[3];
  my $dbPath = $Fld[4];
  $home_dir = $ENV{HOME};
  $ENV{CCM_ENGLOG} = "$home_dir/ccm_eng_" . "$dbId" . ".log";
  $ENV{CCM_HOME} = "$ccm_home";
  $ENV{CCM_UILOG} = "$home_dir/ccm_ui_" . "$dbId" . ".log";
  $ENV{PATH} = $ENV{PATH} . ":" . "$ccm_home/bin";
  `/common/gm/scripts/ccm_ini_init $dbId`;
  
  my $res=`$ccm_home/bin/ccm start -nogui -f $home_dir/.ccm_$dbId.ini 
+-d $dbPath/$dbName -m -q -h $dbEnghost`;
  print LOG $res; # Nothing is being printed
  if ($res ne "") {
    $ENV{CCM_ADDR}=$res;
    return 0;
  } else {
    return 1;
  }
  return 0; # subroutine not even returning to the caller with an inva
+lid status
}
