PI54410: A LENGTHY ERROR MESSAGE RETURNED FROM A PERL TRIGGER SCRIPT CAN CAUSE RATIONAL CHANGE TRANSITION TO HANG

APAR status

• Closed as program error.

Error description

• A lengthy error message returned from a Perl trigger script can
  cause Rational Change transition to hang.
  
  
  When a perl script is used in a pre-transition trigger, if it
  returns an error message exceeduing a certain size, it will
  cause the submission hang without popping up the expected window
  containing the error message.  The progress indicator will
  continue to oscillate, and no errors or warnings are written to
  the event log.
  
  The length of the error message that creates this behavior
  varies from environment to environment.  Below is sample code
  that illustrates the issue when $records is set sufficiently
  high:
  
  ----------------------------------------------------------------
  ---------------
      use warnings;
      use strict;
  
      my $records = 15;
  
      if ($records ne 0)
      {
          my $error_message = 'Duplicate Links: ';
          for (my $i = 0; $i < $records; $i++)
          {
  			$error_message .= "<a
  href=\"http://www.ibm.com/support\">Link $i</a> ";
          }
          $error_message .= ")!\n";
          die($error_message);
      }
      else
      {
          exit(0); #Success
      }
