Description (partial)

Symptom:
When doing a DNS lookup for SSH pubkey the active switch will not sync the config correctly. To recover the standby switch will reload. The bulk sync failure message is displayed in syslog.

Conditions:
configuring the ssh-pubkey-server using the DNS name and not an IP address the active member will not sync the configuration. When this happens the standby switch will reload to recover. A bulk sync failure message is seen in the syslog.

/// Message from Syslog///
