The default method for calculating the number of connections allowed per RPC service arbitrarily limits single-threaded services to 80 connections. This is too low for services like lockd and artificially limits the number of TCP clients that it can support. Have lockd set a default sv_maxconn value to 1024 (which is the typical default value for RLIMIT_NOFILE. Also add a module parameter to allow an admin to set this to an arbitrary value.
