Nous utilisons Apache 2.4 sous CentOS en frontend de serveurs Apache Tomcat 8. Les serveurs Apache jouent le rôle de Balancer vers les Tomcat.
Nous avons donc une adresse IP Virtuelle (VIP) fourni par KeepAlived et deux serveurs sur lesquels sont installé un Apache HTTPD et un Apache Tomcat.
J'ai vraiment du mal à comprendre la provenance de ces erreurs...
D'avance merci,
