random token re-used in subsequent requests

[Vincent Veyron]

Hi,

I use the code shown here :

http://pastebin.com/6YL9FWGX

in a mod_perl handler.

At line 57, $args->{_token_id} ||= ... generates a random token that is used to 
uniquely identify the request (users may reload the URL in two different 
windows), and added to the request's arguments. 

Out of five different servers, the code works fine on four machines, and a 
different token is generated every time the page is loaded or re-loaded. On one 
server however, a previous token is being re-used. The servers are not 
identical, but all run the same up-to-date Debian Jessie, using the same 
distribution packages of Apache and mod_perl

Below is what is printed in the error log of the faulty system by Data::Dumper; 
as you can see, on the third iteration, the first token is reused.

Before : $VAR1 = {
          'id_entry' => '16007',
          'mois' => 0,
          'open_journal' => 'Fournisseurs'
        };
After : $VAR1 = {
          '_token_id' => 'Gh63Y2J9YYaNuReIsI8JAEj9oCY39oiy', 
<------------------------------------- token 1
          'id_entry' => '16007',
          'mois' => 0,
          'open_journal' => 'Fournisseurs'
        };
Before : $VAR1 = {
          'id_entry' => '16007',
          'open_journal' => 'Fournisseurs',
          'mois' => 0
        };
After : $VAR1 = {
          'open_journal' => 'Fournisseurs',
          'mois' => 0,
          'id_entry' => '16007',
          '_token_id' => 'EHL2mm1LvmFIgPeYEFYO8dKt71lWiwkP' 
<------------------------------------- token 2
        };
Before : $VAR1 = {
          'mois' => 0,
          'open_journal' => 'Fournisseurs',
          'id_entry' => '16257'
        };
After : $VAR1 = {
          'open_journal' => 'Fournisseurs',
          'mois' => 0,
          'id_entry' => '16257',
          '_token_id' => 'Gh63Y2J9YYaNuReIsI8JAEj9oCY39oiy' 
<------------------------------------- token 1 again
        };

What can I do to find the cause of this misbehaviour?
