Ok so I have reports that NFS may also be a red herring, however I've found a patch that seems to greatly mitigate issues when testing with the reproducer I was provided. So I'm going to provide a test build with that for 3.13, 3.16, 3.19 and users can give me feedback if that helps.
In addition, if you still can reproduce the issue with this fix, it would be helpful to know more about your test case. I'd like to handle any of these issues as a separate bug.
