Each snapshot can grow up to its base disk's provisioned size, so it's not very surprising that disk space gets exhausted with multiple snapshots, and a lot of changes.

To find out what can/should be done, please provide some information. To get the required information, temporarily enable SSH on the host to allow putty and WinSCP to connect to it.

The VM's folder is "/vmfs/volumes/datastore1/vu18"

• connect to the host using putty, and run ls -lisa > filelist.txt in the VM's folder
• use WinSCP, and download filelist.txt as well as all the descriptor .vmdk files (the ones without "ctk", "flat", "delta", or "sesparse" in their names)
• compress/zip the downloaded files, and attach the .zip archive to a reply post
