Same question as before: What percentage of the system RAM is Nuke being
allowed to use, and how much RAM does that actually equate to? ('cache
memory usage' a.k.a. 'CacheLimit' knob in the Preferences).
If you're hitting the ceiling of Nuke's allotted system RAM, your nodes will
start panic-swapping, and when Nuke shuts down, Windows will need to free
that swapped virtual memory before the program can exit (which can take a
loooong time on a single spinning-metal drive).

Subject: Re: [Nuke-users] Nuke slow to close on Windows 7
We set the cache explicitely on the D: drive of each machine.
We launch only one render per machine with multithread.
The swap is set to the same min/max on every machine.
Anything else? This is the kind of bug that can take me weeks to find.

Set the swap to 25 gig and have the min/max the same so windows
doesn't keep on dynamically resizing it. Also make sure your cache is
explicitly set. Especially if you have floating profiles under
windows then you run into the problem where lame windows puts tmp in a
directory which lives on the server and or it gets copied back to the
server every time the system logs out.
3rd, on your farm are you launching a render per core or are you
multithreading? I would multithread if you don't have the ram since a
frame per core uses far more ram.
