Here are the error messages:
0xc1d0000b due to failure pre-committing: Out of memory
Could not stat LFB on volume VRTX_Datastore: Out of memory
Heap vmfs3 already at its maximum size
exceeded for caller Fil3_FileIOInt
Max no space retries (10) exceeded for caller Fil3_SetFileLength (status 'No space left on device')
There is no more space for virtual disk 'VMNAME-HERE.vmdk'. You might be able to continue this session by freeing disk space on the relevant volume, and clicking Retry. Click Cancel to terminate this session.
Here is what I did. Transfer some of the VM off the Host to another host.
