Zone transfer daemon, zxfrd, will restart endlessly until it is stopped. On the console there will be emergency system alerts every few seconds saying that zxfrd is restarting. Because of the frequency of these alerts, it will be impossible to use the console for anything. In addition, zone transfers initiated by the BIG-IP will not succeed.
The BIG-IP will not be able to transfer zone data from other servers and the TMOS console will be unusable until zxfrd is stopped.
If BIG-IP loses power in the middle of a DNS zone transfer, zone data may be corrupted upon booting up. This results in a nonfunctional zxfrd.
Run the following commands in the console of your affected BIG-IP: bigstart stop zxfrd cd /var/db && rm -f tmmdns.bin zxfrd.bin bigstart start zxfrd
With this fix, zone data is no longer susceptible to corruption from power loss.
