Topic: erreur accès page 404

Bonjour,
J’héberge un site sur CMS ametys 3.8.1
Ma config :
*Back office 
  - Debian 8
  - Apache 2.4.10
  - Java 7
  - tomcat 8.0.32
  - mysql 14.14
*Front office
 - Debian 9
 - Apache 2.4.25
 - Java 8
 - tomcat 9.0.14
 - mysql 14.14

Depuis que j'ai mis à jour mon front office en debian 9, j'ai de gros soucis avec mes pages d'erreur.
Lorsqu'une URL mal formée est envoyée, ma page d'erreur ne s'affiche pas, j'ai ce message d'Apache :
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Ce problème génère aussi d'importants nombres d'écritures au niveau des logs: le servlet-engine.log du back office pèse plusieurs Giga et mon disque arrive à saturation si je ne le purge pas très fréquemment.
Voici un extrait de ce journal :

J'ai aussi des logs similaires pour l'accès à la page 500.
J'ai vérifié les droits du dossier tomcat, du dossier error où se trouve ma page 404.html

Avez-vous une idée pour orienter mes recherches : config apache ou tomcat  du back-office ou  du front office ??
