Do you know what a file descriptor is?

There is something about it here:  
http://www.freebsd.org/doc/en/books/handbook/configtuning-kernel-limits.html  
(search for 'file descriptor')
Or more info in here:  
https://www.google.nl/search?q=freebsd+Out+of+file+descriptors

It mainly says that you have more files open than your system is  
configured to allow. This is often produced by a bug in a program which  
does not close some files properly.
