ZCM 11.2.3a Image upload error [directory does not exist]

We are uploading a number of images to the server.
A lot of these are large images and the workstation has been build as a VMWare workstation.
So far with the exception of one, all have uploaded successfully.

One image is failing to upload when it is about halfway through. The error displayed on the workstation says "Directory not found"

Looking at the novell-pbserv.log I see the following error message related to the image upload.

RWCC unknown compression command code: 0x4000000 (67108864)
RIP2 RWCC faiolure 3, 1851,

Any help /ideas appreciated.

Thanks
Mark
