What OS are you on? This can be easily fixed on Linux (and I believe OSX) by
increasing the system limit (which tends to be quite low by default if I
recall). Since Nuke seems to be somewhat lazy about closing files and
destroying FileReader instances, this could definitely be seen even in simple
comps with long timelines like yours; though, as Michael mentioned, it most
often shows up in situations where lots of temporal operations or input
splitting are going on.

Subject: Re: [Nuke-users] Too many open files
Do you have a bunch of FrameHolds in the script? That seems to be a catalyst
for this issue popping up.

Quite painful and common. Seems Nuke gets 'congested' with some temporal
operations, more so then shake did in my experience.
