VNX for file - nfs - snapshots

Hi, VNX for file, nfs share mounted on a vdm.

Automatic snapshots scheduled at .00 every hour.

From VNX I can see snapshots as expected:

but from a linux client mounting that file system I can see some snapshot which are not on VNX (!!) - highlighted in bold.

These last two "strange" snapshots can vary from a specific time to the next run of a snapshot job.

Any idea what can I check on the client side? Linux Ubuntu and Solaris clients behave the same.

EMC support already involved and nothing found on the VNX side.

Thanks.
