AVR data in MySQL might grow to fill all disk space.


MySQL stops responding. Site might experience down time due to full disk.


This might occur when DNS table receives a large number of entries that are not being evicted when they are no longer needed.


If monitoring disk space and AVR data takes more than 70% of the space, reset AVR data by running the following commands sequentially: -- touch /var/avr/init_avrdb. -- bigstart restart monpd.

Fix Information

In this release, the system handles AVR data in MySQL so that database size no longer grows beyond a certain point.
