214,269 files

Why Jake, why!? 😂

Nearly all of those files are used for KV Store entries ☺️

We typically recommend defining a .fastlyignore and adding patterns for files/directories to skip. I appreciate that's not going to necessarily help your particular issue though.

Have you tried bumping your file descriptor limits (ulimit -n)? Even if this works I suspect keeping tabs of so many files is going to be very slow.
