Thanks Neil for review and efforts :) No one is perfect so no worries. But to be honest, this bug was not really easy to catch, as it's also linked to QNAP stuff... At the end we have a decent workaround and that's enough for the coming weeks. And BTW, it's on my TODO list to replace QNAP by a self-made NFS server: at least, I'll know who to blame 8^D Best, St���phane
