Issue Description

This is a bug in Solaris which causes Apache to dump core if nsswitch.conf and system services are not properly configured. This also affects ZRM Server running on Solaris 10. For more information, please see the following Apache bug:

https://issues.apache.org/bugzilla/show_bug.cgi?id=27525

Resolution

Configure the VirtualHost entry in ssl.conf with the exat IP address of the server as shown in the following steps.

  1. Stop ZMC
/etc/init.d/zmc_aee stop

2. Edit /etc/nsswitch.conf to ensure that the hosts entry includes dns, such as:

hosts: files dns

3. If applicable, edit /etc/inetd/hosts. For example, if installed on a server with IP address “192.168.15.183“, hostname “sol10vm“, and FQDN “sol10vm.zmanda.com“, please include an entry as follows:

192.168.15.183 sol10vm.zmanda.com sol10vm loghost

4. Edit /opt/zmanda/amanda/apache2/conf/ssl.conf to replace

<VirtualHost _default_:443>

with

<VirtualHost *:443>

5. Enable NSCD

svcadm enable svc:/system/name-service-cache:default

Start ZMC

/etc/init.d/zmc_aee start
