Bug Description
This is very similar to bug 585657: https:/
Difference is my server doesn't freeze, it closes the socket. System integrity is still responsive.
I'm running NFS version 4 on Ubuntu 14.04.4 LTS and during large rsync file copies (200MB+) they die midway. This is killing my zimbra email backups :(. I haven't had the system freeze during this scenario but what ends up happening is the copy fails on the client side and then my NFS server shuts the socket down due to excessive failures. Smaller file copies work perfectly fine.
Here are the client/server logs.
