MDV volume size increasing abnormally and CIFS auditing not working

• ONTAP 9 and later
• CIFS auditing enabled

• MDV volume size increasing more than 2GB and consolidation job is not running on the node where MDV volume is located.
• Due to this, CIFS auditing is not working and no further log destination file is being generating.
• MDV volume full or nearly full alerts seen in ems logs:
