They are dynamically allocated.
On my system:
~ %% cat /proc/sys/fs/file-nr
913 82 4096
~ %%
913 open file structures
all but 82 in use
will allocate more as needed until 4096 allocated

I'm guessing running out of memory. Kernel memory cannot be swapped, so
if the kernel is using 126MiB on a 128MiB system, you'll swap just as
bad as if your system only had 2 MiB (ignoring the minor detail that
remotely recent versions of Linux won't boot with that little memory).
