DNS Express daemon, zxfrd, cannot start if its binary cache has filled the /var directory.


Zxfrd will continually restart.


Using DNS Express and the /var directory is filled.


No workaround, but if in zxfrd restart loop due to this issue you can mitigate the issue by deleting /var/db/tmmdns.bin and then running the following command: bigstart restart zxfrd.

Fix Information

DNS Express daemon, zxfrd, will now check to see if /var is full or if the tmmdns.bin database file is corrupted. If either of these conditions is true, zxfrd will not continually restart.
