Symptoms

After a server reboot, CyberSense services exhibit prolonged startup times, taking up to 15 minutes in some instances.
Additionally, the CyberSense UI is observed to have degraded performance.

Cause

The issue is related with a nameserver entry in the /etc/resolv.conf pointing to null.
This occurs in environments where DNS is not configured in the vault.

Resolution

In order to resolve this issue, remove any line from /etc/resolv.conf like the following:

nameserver null

Then restart the CyberSense services with command:

dservice restart all

 

For the SUSE operating systems, it is all necessary to prevent that entry returning after reboots.

Modify the /etc/sysconfig/network/config file.

If a DNS host is available in the vault, configure that IP address in the following line:

NETCONFIG_DNS_STATIC_SERVERS="<DNS HOST IP>"

Save the file.

This ensures the resolv.conf file has the correct entry after reboots.

OR

If there is no DNS service configured in the vault environment, change the following line from:

NETCONFIG_DNS_POLICY="auto"

To:

NETCONFIG_DNS_POLICY=""

Save the file.

This prevents auto configuration attempts in future reboots.
