/var/lib/mysql mount point gets full.


While other dimensions are being collapsed correctly, the Device ID field is not being collapsed causing the growth in size. -- High disk usage. -- Frequent need to clear AVR data.


Many combinations of IP addresses, Device IDs (and other ASM dimensions) in traffic over very long period of time (potentially weeks/months).


Manually delete AVR mysql partitions located in /var/lib/mysql/AVR.
