XFS corruption on RHEL 6.3 XFS volume

Hello,
So I'm using a RHEL 6 based storage solution from Dell called NSS. It's a RHEL high availability setup with 260~TB logical volume formatted XFS.

The filesystem has corrupted twice this week and is repairable only with xfs_repair -L. The crash seems to happen while one user is deleting a large amount of files (80TB). During both crashes, the deletion was occurring.

If anyone could suggest a configuration issue or bug with XFS in this release of RHEL, or any suggestions, I would greatly appreciate it!
