Since you are on a Linux system, use a little utility called "lsof"
This one will list all the file descriptor associated with your process.
When you get the output, it will point you to where you are using up all
your file descriptors.
Also, check your "ulimit -n" setting for the user running

It was previously set to 1024, and I quadrupled it. When you say ulimit

I don't seem to have the command lsof, I'll try and apt-get it.

Setting a limit with ulimit is "sticky" (i.e. persistent), so there's
no need to stick it in the startup script.
