NonStop TMF auditdump management

[Kee_aus]

We are noticing that the auditdump seems to be hitting one of the disk rather than spreading them out. The dsap shows %tage free on the master auditdump.
$AUD02 Y 69
$AUD03 Y 58
$AUD04 Y 13

$AUD04 is constantly dipping below 10% but stays around the teens or less.

Note the dsap bysubvol shows only auditdumps in those disk, ie ZA* subvols. So we know the data is purely TMF.
TMFCOM info auditdump master
Auditdump Configuration:
Master: enabled, medium disk
 DiskMedia \NODE1.$AUD02.ZA, \NODE1.$AUD03.ZA, \NODE1.$AUD04.ZA
UseVolumeCpu Off
Question is why is TMF doing this and is there anything that can be done?
