Depends a bit on your comm loop, and why you need very many
filedescriptors.

The filedescriptor limit servers two purposes

a) OS imposed limit, to avoid bringing down the machine by hitting os
total limits..

b) Load limitation, making Squid stop accepting new connections if it is
already processing too many.

'b' might risk allowing your Squid to spiral down quite far if the
number of filedescriptors is very large, much larger than you actually
need.

Yes.. have compiled Squid with some hundreds of thousand
filedescriptors, but only for experimental purposes.
