SANHQ 3.1 reporting 100% usage on NAS volumes

Since upgrading to 3.1, SANHQ has been alerting for Critical In-use space on 2 volumes. There are 6 NAS volumes on that group and there's enough space for the NAS. I believe the data distribution on those volumes is done automatically by the controller, so this distribution would be considered normal under these circumstances. Should I be worried that SANHQ is alerting me on those 2 volumes? is there something I can do to improve data distribution across NAS volumes? lastly, if this is considered normal, is there a setting on SANHQ to prevent this 'false positive' alert?
