seeing NTFS warnings every time a SAN snapshot is taken. Please HELP

looked for some info on the NTFs warning. did not find much so I sent an email to Dell equal logic:

Good morning. We are getting NTFS warning with every SAN snap shot this is taken. I am being told that this is not supposed to happen.
This occurs on all the servers. I have little prior knowledge on SANS. Any insight would help.

We have the following configuration:

Windows 2008r2 server
 Dell EqualLogic SAN firmware version 9.0.5

-2 snapshots retained on Saturdays at 2am
- A file server has a weekly snapshot and a daily snapshot
-exchange server also has a weekly snapshot and a daily snapshot
-the domain controller, citrix servers and vcenter server also has daily and weekly snapshots.

We do know that citrix and Server 2008 R2 is not causing the issue. I don’t know much else and I am not given much else information about the environment.
