ReFS memory leak with Storage Spaces

I have a Storage Space with 6 10 TB drives. The array is formatted ReFS (4KB clusters). When copying large files to the drive (30 to 40 GB each), available RAM will slowly decrease (system has 16 GB) until the system becomes unresponsive and crashes.
This did not happen when the Storage Space was formatted with NTFS. I opened a case (1400731631) but they said they were unable to do anything. Is there a fix for this? This page seems to no longer apply:

ReFS is not listed as a format option when creating a mirrored storage space

I have two Windows 10 computers. Both are upgraded from Windows 7. When I create a storage space on one of these computers, I can format a two-way mirrored storage space as ReFS, but the other computer only lists NTFS for the same two drives.

If I create a mirrored ReFS space on the first computer and then plug in the drives into the second computer, Windows pops up an error message saying "This version of Windows doesn't support the ReFS format on drive".

How can I enable ReFS on the second computer?

 

Will ReFS / Storage Spaces configuration works correctly with Windows 10?

Old title: Windows 10 and ReFS

I've been unable to find a clear-cut answer to my question. I'm running Win 8.1 Pro and I use 2 secondary HDs for my 'data'. These drives are formatted ReFS and configured in a Storage Spaces mirrored configuration. I think I'm ready to upgrade my Win
8.1 Pro to Win 10 but I'm looking for reassurance that the ReFS / Storage Spaces configuration is going to still work just fine. Will this be the case?

(My primary drive is SSD NTFS)
