Symptoms

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

Impact

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

Conditions

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

Workaround

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.
