ioctl error after snapshot creation

Hi all,

I have VM with a 10TB vmdk, which I want to backup using Commvault Simpana.

The snapshot gets created successfully, but after that only errors are returned. I found this snippet in the hostd.log:

This error seems to occur when the vmdk size is bigger than 5TB., there is plenty of room for snapshot overhead on the datastore.

The CommVault logs only show 'possible VDDK deadlock encountered', the used VDDK version is 5.5.1

The host is running ESXi version 5.5.0-2143827

Does anybody ever experienced anything like this?

Can you create a "normal" snapshot with Snapshot Manager from vCenter/ESXi?

Creating/deleting a snapshot isn't giving any trouble.

What I gather from the logs, it seems the soapadapter (api?) has problems reading/accessing the delta disk.

All other machines snapshot and backup just fine.
