• The VERDE User Console and the VERDE Management Console are not available.
• When investigating on the VERDE Server(s) it appears that Tomcat failed to start.
• When attempting to restart Tomcat, it fails to start with messages similar to the output below:

root@verde-srv2:/var/log/verde/1# /usr/lib/verde/bin/verde-start-tomcat.sh start

Starting VERDE tomcat...

Using CATALINA_BASE:   /usr/lib/verde/etc/apache-tomcat

Using CATALINA_HOME:   /usr/lib/verde/etc/apache-tomcat

Using CATALINA_TMPDIR: /var/lib/verde/mc/tmp

Using JRE_HOME:        /usr

Using CLASSPATH:       /usr/lib/verde/etc/apache-tomcat/bin/bootstrap.jar

root@verde-srv2:/var/log/verde/1# *** buffer overflow detected ***: /usr/bin/java terminated

This error can be triggered by IPV6  being enabled in the Linux kernel network stack.

SOLUTION:

Disable IPv6 on the VERDE server by writing 1 in the /proc/sys/net/ipv6/conf/all/disable_ipv6 file. 

By default, the value in the disable_ipv6 file is 0.
