I can tell you that we use X-SAN and render to PROres all day long and aren’t seeing this issue.
Trouble shooting something like this is a PITA, but my suggestion is to start at the begining with a clean project, a sample of what you’re trying to accomplish and see if you can repeat the problem. Renders
can get lost, but it’s usually due to moving projects, systems, or a change in the “render” folder.
I don’t think someone is going to solve this with a post on this forum. You really need someone sitting on your system to take a close look at what you’re doing and track the results.
Wish I had an easier response…
