I'm pretty sure it's not that - the error message was 'Too many
open files' and not 'Too many open files in system', and I think
I would've noticed if the kernel had run out of file descriptors
- it splats a message on the console when that happens, for a start.

and 4.9.4PL1 doesn't have any security holes or serious bugs I'm
aware of so I'm sticking with it for the moment ;-).
